Notes to Table 1–21:
(1) This specification is valid for transmitter output jitter specification with a maximum total jitter value of 112 ps, typically for 3.125 Gbps SRIO and XAUI
protocols.
(2) The minimum reconfig_clk frequency is 2.5 MHz if the transceiver channel is configured in Transmitter Only mode. The minimum reconfig_clk frequency
is 37.5 MHz if the transceiver channel is configured in Receiver Only or Receiver and Transmitter mode.
(3) The device cannot tolerate prolonged operation at this absolute maximum.
(4) The rate matcher supports only up to ±300 parts per million (ppm).
(5) Supported for the N148, F169, and F324 device packages only.
(6) Supported for the F484, F672, and F896 device packages only. Pending device characterization.
(7) To support CDR ppm tolerance greater than ±300 ppm, implement ppm detector in user logic and configure CDR to Manual Lock Mode.
(8) Asynchronous spread-spectrum clocking is not supported.
(9) For the EP4CGX30 (F484 package only), EP4CGX50, and EP4CGX75 devices, the CDR ppl tolerance is ±200 ppm.
(10) Time taken until pll_locked goes high after pll_powerdown deasserts.
(11) Time that the CDR must be kept in lock-to-reference mode after rx_analogreset deasserts and before rx_locktodata is asserted in manual mode.
(12) Time taken to recover valid data after the rx_locktodata signal is asserted in manual mode (Figure 1–2), or after rx_freqlocked signal goes high in
automatic mode (Figure 1–3).
(13) Time taken to recover valid data after the rx_locktodata signal is asserted in manual mode.
(14) Time taken to recover valid data after the rx_freqlocked signal goes high in automatic mode.
(15) To support data rates lower than the minimum specification through oversampling, use the CDR in LTR mode only.
