DESCRIPTION & APPLICATIONS
G576 VCXOs are packaged in the industry-standard 7 x 5 x1.8mm 6
pad SMD package. G series VCXOs use fundamental mode crystal
oscillators for low phase noise. Applications include phase lock loop,
SONET/ATM, set-top boxes, MPEG , audio/video modulation, video
game consoles, Fibre Channel, FPGAs, Data Acquisition and HDTV.
