G62 CMOS

VCXO

Frequency range 0.625MHz to 50.0MHz
CMOS/TTL Output
Supply Voltage 5.0 V or 3.3 VDC
Integrated Phase Jitter 1ps typical
Low cost unit

DESCRIPTION

G62 VCXOs, are packaged in a miniature 11.4mm x 9.6mm x 2.5mm
6 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, set­top boxes, MPEG , audio/video modulation, video game consoles and
HDTV.

Output Voltage LOW (0): 10% Vdd maximum
Control Voltage Centre
+3.3VDC: 1.65V
+5.0VDC: 2.5V
Control Voltage Range
+3.3VDC: 0.3V to 3.0V
+5.0VDC: 0.5V to 4.5V
Pulling Range
