Maximum Allowed Overshoot and Undershoot Voltage

During transitions, input signals may overshoot to the voltage listed in the following table and undershoot to –2.0 V for input currents less than 100 mA and periods shorter than 20 ns.

The maximum allowed overshoot duration is specified as a percentage of high time over the lifetime of the device. A DC signal is equivalent to 100% duty cycle.

For example, a signal that overshoots to 4.00 V can only be at 4.00 V for ~15% over the lifetime of the device; for a device lifetime of 10 years, this amounts to 1.5 years.

DC Characteristics

Supply Current and Power Consumption

Altera offers two ways to estimate power for your design—the Excel-based Early Power Estimator (EPE) and the Quartus^® Prime PowerPlay Power Analyzer feature.

Use the Excel-based EPE before you start your design to estimate the supply current for your design. The EPE provides a magnitude estimate of the device power because these currents vary greatly with the resources you use.

The Quartus^® Prime PowerPlay Power Analyzer provides better quality estimates based on the specifics of the design after you complete place-and-route. The PowerPlay Power Analyzer can apply a combination of user-entered, simulation-derived, and estimated signal activities that, when combined with detailed circuit models, yields very accurate power estimates.

³⁰ Transceiver Speed Grade 5 covers specifications for Cyclone^® V GT and ST devices.

³¹ Differential LVPECL signal levels must comply to the minimum and maximum peak-to-peak differential input voltage specified in this table.

³² The reference clock frequency must be ≥ 307.2 MHz to be fully compliance to CPRI transmit jitter specification at 6.144 Gbps. For more information about CPRI 6.144 Gbps, refer to the Transceiver Protocol Configurations in Cyclone^® V Devices chapter.

³³ REFCLK performance requires to meet transmitter REFCLK phase noise specification.

³⁴ Altera recommends increasing the V_{CCE_GXBL} and V_{CCL_GXBL} typical value from 1.1 V to 1.2 V for Cyclone^® V GT and ST FPGA systems which require full compliance to the PCIe Gen2 transmit jitter specification. For more information about the maximum full duplex channels recommended in Cyclone^® V GT and ST devices under this condition, refer to the Transceiver Protocol Configurations in Cyclone^® V Devices chapter.

³⁵ Altera recommends increasing the V_{CCE_GXBL} and V_{CCL_GXBL} typical value from 1.1 V to 1.2 V for full compliance to CPRI transmit jitter specification at 4.9152 Gbps ( Cyclone^® V GT and ST devices) and 6.144 Gbps ( Cyclone^® V GT and ST devices only). For more information about the maximum full duplex channels recommended in Cyclone^® V GT and ST devices for CPRI 6.144 Gbps, refer to the Transceiver Protocol Configurations in Cyclone^® V Devices chapter.

³⁶ The transmitter REFCLK phase jitter is 30 ps p-p at bit error rate (BER) 10^-12.

³⁷ The maximum supported clock frequency is 100 MHz if the PCIe hard IP block is enabled or 125 MHz if the PCIe hard IP block is not enabled.

³⁸ To support data rates lower than the minimum specification through oversampling, use the CDR in LTR mode only.

³⁹ The device cannot tolerate prolonged operation at this absolute maximum.

⁴⁰ The differential eye opening specification at the receiver input pins assumes that you have disabled the Receiver Equalization feature. If you enable the Receiver Equalization feature, the receiver circuitry can tolerate a lower minimum eye opening, depending on the equalization level.

⁴¹ The AC coupled V_ICM = 650 mV for Cyclone V GX and SX in PCIe mode only. The AC coupled V_ICM = 750mV for Cyclone V GT and ST in PCIe mode only.

⁴² t_LTR is the time required for the receive clock data recovery (CDR) to lock to the input reference clock frequency after coming out of reset.

⁴³ t_LTD is time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high.

⁴⁴ t_{LTD_manual} is the time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high when the CDR is functioning in the manual mode.

⁴⁵ t_{LTR_LTD_manual} is the time the receiver CDR must be kept in lock to reference (LTR) mode after the rx_is_lockedtoref signal goes high when the CDR is functioning in the manual mode.

⁴⁶ The rate matcher supports only up to ±300 parts per million (ppm).

⁴⁷ The Quartus^® Prime software allows AC gain setting = 3 for design with data rate between 614 Mbps and 1.25 Gbps only.

Transmitter Pre-Emphasis Levels

The following table lists the simulation data on the transmitter pre-emphasis levels in dB for the first post tap under the following conditions:

Low-frequency data pattern—five 1s and five 0s
Data rate—2.5 Gbps

The levels listed are a representation of possible pre-emphasis levels under the specified conditions only and the pre-emphasis levels may change with data pattern and data rate.

Cyclone^® V devices only support 1st post tap pre-emphasis with the following conditions:

The 1st post tap pre-emphasis settings must satisfy |B| + |C| ≤ 60 where |B| = V_OD setting with termination value, R_TERM = 100 Ω and |C| = 1st post tap pre-emphasis setting.
|B| – |C| > 5 for data rates < 5 Gbps and |B| – |C| > 8.25 for data rates > 5 Gbps.
(V_MAX/V_MIN – 1)% < 600%, where V_MAX = |B| + |C| and V_MIN = |B| – |C|.

Exception for PCIe Gen2 design:

V_OD setting = 50 and pre-emphasis setting = 22 are allowed for PCIe Gen2 design with transmit de-emphasis –6dB setting (pipe_txdeemp = 1’b0) using Altera PCIe Hard IP and PIPE IP cores.
V_OD setting = 50 and pre-emphasis setting = 12 are allowed for PCIe Gen2 design with transmit de-emphasis –3.5dB setting (pipe_txdeemp = 1’b1) using Altera PCIe Hard IP and PIPE IP cores.

For example, when V_OD = 800 mV, the corresponding V_OD value setting is 40. The following conditions show that the 1st post tap pre-emphasis setting = 2 is valid:

|B| + |C| ≤ 60→ 40 + 2 = 42
|B| – |C| > 5→ 40 – 2 = 38
(V_MAX/V_MIN – 1)% < 600%→ (42/38 – 1)% = 10.52%

To predict the pre-emphasis level for your specific data rate and pattern, run simulations using the Cyclone^® V HSSI HSPICE models.

⁵² This specification is limited in the Quartus^® Prime software by the I/O maximum frequency. The maximum I/O frequency is different for each I/O standard.

⁵³ The VCO frequency reported by the Quartus^® Prime software takes into consideration the VCO post-scale counter K value. Therefore, if the counter K has a value of 2, the frequency reported can be lower than the f_VCO specification.

⁵⁴ This specification is limited by the lower of the two: I/O f_MAX or F_OUT of the PLL.

⁵⁵ High bandwidth PLL settings are not supported in external feedback mode.

⁵⁶ A high input jitter directly affects the PLL output jitter. To have low PLL output clock jitter, you must provide a clean clock source with jitter < 120 ps.

⁵⁷ F_REF is f_IN/N, specification applies when N = 1.

⁵⁸ Peak-to-peak jitter with a probability level of 10^–12 (14 sigma, 99.99999999974404% confidence level). The output jitter specification applies to the intrinsic jitter of the PLL, when an input jitter of 30 ps is applied. The external memory interface clock output jitter specifications use a different measurement method and are available in Memory Output Clock Jitter Specification for Cyclone^® V Devices table.

⁵⁹ This specification only covers fractional PLL for low bandwidth. The f_VCO for fractional value range 0.20–0.80 must be ≥ 1200 MHz.

⁶⁰ External memory interface clock output jitter specifications use a different measurement method, which are available in Memory Output Clock Jitter Specification for Cyclone^® V Devices table.

⁶¹ This specification only covers fractional PLL for low bandwidth. The f_VCO for fractional value range 0.05–0.95 must be ≥ 1000 MHz.

⁶² The cascaded PLL specification is only applicable with the following conditions:

Upstream PLL: 0.59 MHz ≤ Upstream PLL BW < 1 MHz
Downstream PLL: Downstream PLL BW > 2 MHz

Memory Block Performance Specifications

To achieve the maximum memory block performance, use a memory block clock that comes through global clock routing from an on-chip PLL and set to 50% output duty cycle. Use the Quartus^® Prime software to report timing for the memory block clocking schemes.

When you use the error detection cyclical redundancy check (CRC) feature, there is no degradation in f_MAX.

Periphery Performance

This section describes the periphery performance, high-speed I/O, and external memory interface.

Actual achievable frequency depends on design and system specific factors. Ensure proper timing closure in your design and perform HSPICE/IBIS simulations based on your specific design and system setup to determine the maximum achievable frequency in your system.

High-Speed I/O Specifications

When J = 1 or 2, bypass the serializer/deserializer (SERDES) block.

For LVDS applications, you must use the PLLs in integer PLL mode. This is achieved by using the LVDS clock network.

⁶³ Clock boost factor (W) is the ratio between the input data rate and the input clock rate.

⁶⁴ The F_max specification is based on the fast clock used for serial data. The interface F_max is also dependent on the parallel clock domain which is design dependent and requires timing analysis.

⁶⁵ The minimum specification depends on the clock source (for example, the PLL and clock pin) and the clock routing resource (global, regional, or local) that you use. The I/O differential buffer and input register do not have a minimum toggle rate.

⁶⁶ The maximum ideal data rate is the SERDES factor (J) × PLL max output frequency (f_out), provided you can close the design timing and the signal integrity simulation is clean. You can estimate the achievable maximum data rate by performing link timing closure analysis. You must consider the board skew margin, transmitter delay margin, and receiver sampling margin to determine the maximum data rate supported.

⁶⁷ You must calculate the leftover timing margin in the receiver by performing link timing closure analysis. You must consider the board skew margin, transmitter channel-to-channel skew, and receiver sampling margin to determine the leftover timing margin.

Memory Output Clock Jitter Specifications

Table 36. Memory Output Clock Jitter Specifications for Cyclone^® V Devices.
The memory output clock jitter measurements are for 200 consecutive clock cycles, as specified in the JEDEC DDR2/DDR3 SDRAM standard.

The memory output clock jitter is applicable when an input jitter of 30 ps (p-p) is applied with bit error rate (BER) 10^–12, equivalent to 14 sigma.

Altera recommends using the UniPHY intellectual property (IP) with PHYCLK connections for better jitter performance.
