DESCRIPTION & APPLICATIONS  
G14 VCXOs are packaged in the industry-standard 14 pin Dual-in-Line  
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.
