VV-701 Voltage Controlled Crystal Oscillator Previous Vectron Model VVC1/VVC2 VV-701 Description Vectrons VV-701 Voltage Controlled Crystal Oscillator (VCXO) is a quartz stabilized square wave generator with a CMOS output. The VV-701 uses fundamental crystals resulting in low jitter performance and a monolithic IC which improves reliability and reduces cost. Features Applications CMOS output VCXO SONET/SDH/DWDM Output Frequencies from 1.544 MHz to 77.760 MHz Ethernet, SynchE 5.0 or 3.3 V Operation xDSL, PCMIA High Impedance Control Voltage Option Digital Video Fundamental Crystal Design with Low Jitter Performance Broadband Access Output Disable Feature Base Stations, Picocells Excellent 20ppm Temperature Stability, 0/70C or -40/85C Operating Temperature Small Industry Standard Package, 7.0x5.0x1.8mm Product is free of lead and compliant to EC RoHS Directive Block Diagram V E/D or NC Output DD Crystal Oscillator V E/D or NC Gnd C Page1 Performance Speci cations Performance Speci cations Table 1.
