EURO

QUARTZ

Frequency range 0.625MHz to 50.0MHz

CMOS/TTL Output

Supply Voltage 5.0 V or 3.3 VDC

Integrated Phase Jitter 1ps typical

DESCRIPTION

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.
