General 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.
