Crystal 1. A clock pulse at f
of two crystal pins) with : -50.10
Crystal 2. If the internal crystal oscillator is used, the second crystal pin is applied
to this output.
VCXO input signal. This signal is compared to clock A(or B) selected inside the
Multi-HDLC .
VCXO error signal. This pin delivers the result of the comparison.
Input Clock A (4096kHz or 8192kHz)
Input Clock B (4096kHz or 8192kHz)
Clock A at 8kHz
Clock B at 8kHz
Data Clock issued from Input Clock A (or B). This clock is delivered by the circuit
at 4096kHz (or 2048kHz). DOUT0/7 are transmitted on the rising edge of thissignal.
DIN0/7 are sampled on the falling edge of this signal.
Frame synchronization for GCI at 8kHz. This clock is issued from FRAME A (or B).
Frame synchronization for V Star at 8kHz
Frame synchronization.This signal synchronizes DIN0/7 and DOUT0/7.
Programmable synchronization Signal. The PS bit of connection memory is read
in real time.
