Function
Line Receiver 2
Analog input from the external transformer.
Selected if LIM1.DRS is cleared.
Receive Data Input Negative
Input for received dual-rail PCM(-) route signal
which is latched with the internally recovered
receive route clock. An internal DPLL extracts
the receive route clock from the incoming data
pulses. The duty cycle of the received signal
has to be close to 50%.
The dual-rail mode is selected if LIM1.DRS
and FMR0.RC1 are set. Input polarity is
selected by bit RC0.RDIS (after reset: active
low), line coding is selected by FMR0.RC(1:0).
Receive Clock Input
Receive clock input for the optical interface if
LIM1.DRS is set and FMR0.RC(1:0) = 00.
Clock frequency: 2.048 MHz (E1) or
1.544 MHz (T1/J1).
RCLKI is ignored if CMI coding is selected.
