WJ VC1001

DRO for OC–192
An RF evolution for OC-192

OC-192 Clock Oscillator for SONET/SDH Systems

The VC1001 provides an ultra-stable, fundamental

9953.28MHz sinewave output signal, suitable for

critical timing applications such as those found in

SONET/SDH OC-192 systems. Typical performance

characteristics include; phase noise of –95dBc/Hz

at 10kHz offset with +1dBm nominal output power,

and a 20MHz tuning range over a –5V to +5V control

voltage. The unit requires +12V @ 175mA and –12V

@ 25mA bias.
