RX_LOCK
Receiver PLL lock indicator. The PLL locks to
REF_CK/RX_REF_CK.
RX_LOCK = 1, receiver PLL frequency is within 300 ppm;
LVCMOS/
RX_LOCK = 0, receiver PLL frequency is larger than 450 ppm; Out

Frequency difference range is adjustable by
SC_LOCK_DIFF[1:0].
RX_D_RP_P³
RX_D_RP_N
10 Gbps CML output, repeat data. This output repeats the data
at the RX_D_P/N inputs when RX_D_RP_Enb = 0. This output
can be used for diagnostic purposes and to evaluate the receiv-
ers limiting amplifier. These pins can be left unconnected if
