EURO QUARTZ
G8 VCXO
DESCRIPTION
Frequency range 0.625MHz to 50.0MHz
CMOS/TTL Output
Supply Voltage 5.0 V or 3.3 VDC
Integrated Phase Jitter 1ps typical
G8 VCXOs, are packaged in an industry-standard, 8 pin Dual in Line
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.
