DESCRIPTION  
OUTLINE & DIMENSIONS  
G42 VCXOs, are packaged in a miniature 11.4mm x 9.6mm x 2.5mm  
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.
