N.C. — No Connect
1 2 SYNCOUT Output
Synchronization Output. An 8kHz output that can be
synchronized to the clock outputs.
2 4 CLKOUT2 Output
Clock Output 2. T1 or E1 carrier clock output referenced to
CLKIN.
3 5 CLKIN Input
Clock Input. Reference Clock Input. CLKOUT1 and CLKOUT2
will be referenced to this clock.
4 7 CLKOUT1 Output
Clock Output 1. T1 or E1 carrier clock output referenced to
CLKIN.
5 9 Vss Supply Ground
6 12 SEL Input Clock Mode Select. Conversion mode select.
7 14 SYNCIN Input
Synchronization Input. Used to synchronize the clock outputs
and SYNCOUT to CLKIN and SYNCIN. SYNCIN should be tied
high or low when not in use.
