DESCRIPTION & APPLICATIONS
G42 VCXOs are packaged in an industry-standard 11.4 x 9.6 x 2.5mm,
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.
