Data Sheet
Receive Input Threshold
Only valid if analog line interface is selected (LIM1.DRS = 0).
“No signal” is declared if the voltage between pins RL1 and RL2 drops
below the limits programmed by bits RIL(2:0) and the received data
stream has no transition for a period defined in the PCD register.
The threshold where “no signal” is declared is programmable by the
RIL(2:0) bits.
See DC characteristics for detail.
Remote Loop Transmit Jitter Attenuator
00 = Normal operation. The remote loop transmit jitter attenuator is
01 = Remote loop active without remote loop transmit jitter

data from pins RL1/2 or RDIP/N or ROID is sent "jitter-free" on
ports XL1/2 or XDOP/N or XOID. The de-jittered clock is
generated by the DCO-X circuitry.
The ternary interface is selected. Multifunction ports RL1/2 and
XL1/2 become analog in/outputs.
The digital dual-rail interface is selected. Received data is
latched on multifunction ports RDIP/RDIN while transmit data is
output on pins XDOP/XDON.
