Master Clock
A reference clock of better than ±32 ppm accuracy in
the range of 1.02 to 20 MHz must be provided on this
pin. The OctalLIU
TM internally derives all necessary
clocks from this master
(see registers GCM(6:1)).

Clock Synchronization of DCO-R
If a clock is detected on pin SYNC the
DCO-R circuitry of the OctalLIU
TM synchronizes to this
1.544/2.048 MHz clock (see LIM0.MAS, CMR1.DCS
and CMR2.DCF). Additionally, in master mode the
OctalLIU
TM is able to synchronize to an 8 kHz reference
clock (IPC.SSYF = 1). If not connected, an internal
pull-up transistor ensures high input level.

8 kHz Frame Synchronization
The optionally synchronization pulse is active high or
low for one 2.048/1.544 MHz cycle (pulse width =
488 ns for E1and 648 ns or T1/J1).

Receive Data Out, port 1
Received data at RL1, RL2 is sent to RDOP, RDON.
Clocking of data is done with the rising or falling edge of
RCLK.
