Function
Reference clock (2.048 MHz) for frequency
comparison to generate the control voltage for
the 16.384 MHz VCXO if Register
FSLIPIV[6]=’1’
Clock from 16.384 MHz VCXO
Receive Frame Sync Pulse from the far end
side (F1). This pulse of 488 ns width marks
timeslot 0 when writing into Elastic Store (e.g.
FALC) to prevent faults in one frame length
mode. To use this pin Register FSLIPIV[5]
must be ’0’.
