Description

The DS4077 is an integrated voltage-controlled crystal oscillator (VCXO) module designed to provide reference clock generation in base stations, telecom/datacom, and wireless applications. The DS4077 is developed using a fundamental quartz crystal plus a unique integrated circuit design. The internal fundamental quartz crystal determines the frequency of operation. Custom frequencies are available. Contact the factory for availability.

The DS4077 is designed for use with applications requiring low phase noise and jitter. Jitter performance of better than 0.8ps RMS is achieved over the 12kHz to 20MHz range. Phase noise performance of better than -125dBc/Hz at 1kHz is achieved with this design.
