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 Low cost unit DESCRIPTION G576 CMOS VCXO 7 x 5 x 1.8mm 6 pad SMD OUTLINE & DIMENSIONS G576 VCXOs, are packaged in a miniature 7mm x 5mm x 1.8mm 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.
