Reference Clock Input (77.76 MHz or 19.44 MHz)
This differential clock input reference is used for the transmit
clock multiplier unit (CMU) and clock data recovery (CDR) to
provide the necessary high speed clock reference for this
device. It will accept either a 77.76 MHz or a 19.44 MHz Differ-
ential LVPECL clock source. Pin CMUFREQSEL determines
the value used as the reference. See Pin CMUFREQSEL for
more details. REFCLKP/N inputs are internally biased to 1.65V.
NOTE:
In the event that TTLREFCLK LVTTL input is used
instead of these differential inputs for clock reference,
the REFCLKP should be tied to ground.
