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 cir-cuit design. The internal fundamental quartz crystal determines the frequency of operation. Custom frequen-cies are available. Contact the factory for availability.

The DS4077 is designed for use with applications requir-ing low phase noise and jitter. Jitter performance of bet-ter than 1ps RMS is achieved over the 12kHz to 80MHz range. Phase noise performance of better than -130dBc/Hz at 1kHz is achieved with this design.
