DESCRIPTION & APPLICATIONS
G8 VCXOs are packaged in the industry-standard 8 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.
