40 Differential LVPECL signal levels must comply to the minimum and maximum peak-to-peak differential input voltage specified in this table.
41 REFCLK performance requires to meet transmitter REFCLK phase noise specification.
42 The maximum peak-to peak differential input voltage of 300 mV is allowed for DC coupled link.
43 The transmitter REFCLK phase jitter is 30 ps p-p (5 ps RMS) with bit error rate (BER) 10-12, equivalent to 14 sigma.
44 To support data rates lower than the minimum specification through oversampling, use the CDR in LTR mode only.
45 The device cannot tolerate prolonged operation at this absolute maximum.
46 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.
47 The AC coupled VICM is 750 mV for PCIe* mode only.
48 For standard protocol compliance, use AC coupling.
49 tLTR is the time required for the receive CDR to lock to the input reference clock frequency after coming out of reset.
50 tLTD is time required for the receiver CDR to start recovering valid data after the rx_is_lockedtodata signal goes high.
51 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.
52 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.
53 The rate match FIFO supports only up to ±300 ppm.
54 The Intel® Quartus® Prime software allows AC gain setting = 3 for design with data rate between 611 Mbps and 1.25 Gbps only.
55 This specification is only applicable to channels on one side of the device across two transceiver banks.
56 The maximum frequency when core transceiver local routing is selected.
57 The maximum frequency when core transceiver network routing (GCLK, RCLK, or PCLK) is selected.
