DESCRIPTION & APPLICATIONS
G324 VCXOs are packaged in an ultra-miniature 3.2 x 2.5 x 0.9mm 4
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.
