Function
Clock Synchronization
If a clock is detected at the SYNC pin the FALC54
synchronizes to this clock 1.544 MHz or
2.048 MHz (if LIM1.DCOC = 1). This pin has to be
connected to
Receive Clock
Extracted from the incoming data pulses
Clock frequency: 1544 kHz
If LIM0.ELOS is set, the RCLK is set high in case
of loss of signal (FRS0.LOS=1).
Receive Data Out
Received data which is sent to the system internal
highway with 4096 kbit/s or 2048 kbit/s (bit
FMR1.IMOD). In 4096 kbit/s mode data is shifted
out in that channel phase which is selected by
register RC0.SICS.The other channel phase is set
in tri-state. Clocking off data is done with the
falling edge of SCLKR. The delay between the
beginning of time-slot 0 and the initial edge of
SCLKR (after SYPR goes active) is determined by
the values of Receive Time-slot Offset
RC1.RTO5 … 0, Receive Clock-slot Offset
RC0.RCO2 … 0 and RC0.RCOS.
