DESCRIPTION
Transmit Serial Data Input:
Differential NRZ data input. See Transmitter Operation section for more info
on different timing modes.
Transmit Serial CMI Data Output:
A CMI encoded data signal conforming to the relevant ITU-T G.703 pulse
templates when properly terminated and transformer coupled to 75ohm
cable.
DESCRIPTION
Receive Serial NRZ Data Output:
Recovered serial data decoded into NRZ format and output at LVPECL levels.
Receive Serial CMI Input:
Receive inputs that should be differentially terminated and transformer
coupled to the coaxial cable.
DESCRIPTION
Reference Clock Input: (Required)
A reference clock input used for clock/data recovery and generation. Can be
a differential 155.52MHz differential LVPECL Input (Type PI) at CKREFP/N
or a single-ended 19.44MHz or 77.78MHz CMOS Input (Type CI) at
CKREFP (tie CKREFN to ground when unused).
Loss of Signal (active-high):
Standards compatible loss of signal indicator.
Power-On Reset (active low):
See Power-On Reset description on use of this pin. Do not pull-up to Vcc.
Notes: 1) Pins are tri-stated during transmit power-down. 2) Pins are
active, but undefined during reset.
Notes: 1) Outputs are squelched during LOS and held low. 2) Pins are active,
but undefined during reset.
