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 Intel recommends increasing the VCCE_GXBL and VCCL_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 Intel recommends increasing the VCCE_GXBL and VCCL_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 VICM = 650 mV for Cyclone® V GX and SX in PCIe* mode only. The AC coupled VICM = 750mV for Cyclone® V GT and ST in PCIe* mode only.
42 tLTR 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 tLTD is time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high.
44 tLTD_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 tLTR_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 Intel® Quartus® Prime software allows AC gain setting = 3 for design with data rate between 614 Mbps and 1.25 Gbps only.
