DESCRIPTION & APPLICATIONS

G536 VCXOs are packaged in the industry-standard 5 x 3.2 x 1.2mm,

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.
