Input reference clock for the PLL (multipurpose PLL or general
purpose PLL) used by the transceiver instance. When configured
with the transmitter and receiver channel configuration in
Deterministic Latency mode, multiple pll_inclk ports are
available as follows.
Configured with PLL PFD feedback—x is the number of channels
selected:
■
■
Configured without PLL PFD feedback:
■
■
PLL (used by the transceiver instance) lock indicator.
PLL (used by the transceiver instance) reset.
■
■
FPGA fabric-transceiver interface clock in bonded modes.

(Note 1)
pll_inclk[x-1..0] are input reference clocks for each
transmitter in the transceiver instance
pll_inclk[x+1..x] are input reference clocks for
receivers in the transceiver instance
pll_inclk[0] is input reference clock for transmitters in
the transceiver instance
pll_inclk[1] is input reference clock for receivers in the
transceiver instance
When asserted, the PLL is kept in reset state.
When deasserted, the PLL is active and locks to the input
reference clock.
