DESCRIPTION
OUTLINE & DIMENSIONS
G534 VCXOs, are packaged in a miniature 5mm x 3.2mm x 1.2mm 4
pad SMD package. Typical phase jitter for G series VCXOs is <1ps,
output CMOS/TTL. G series VCXOs use fundamental mode crystal
osccillators. Applications include phase lock loop, SONET/ATM, set-
top boxes, MPEG , audio/video modulation, video game consoles and
HDTV.
