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.
