VCC1 series 1.8, 2.5, 3.3, 5.0 volt CMOS Oscillator Features CMOS output Output frequencies to 190 MHz rd Low jitter, Fundamental or 3 OT Crystal Tristate output for board test and debug -10/70 or 40/85 C operating temperature Gold over nickel contact pads Hermetically sealed ceramic SMD package RoHS/Lead Free Compliant construction The VCC1 Crystal Oscillator Applications SONET/SDH/DWDM Ethernet, Gigabit Ethernet Storage Area Network Digital Video Broadband Access Microprocessors/DSP/FPGA Description Vectrons VCC1 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, 3.3 or a 5.0 volt supply. rd The VCC1 is uses fundamental or 3 overtone crystals resulting in low jitter performance, f o typically 0.5pS rms in the 12 kHz to 20MHz band. Also a monolithic IC, which improves Output reliability and reduces cost, is hermitically Buffer / sealed.
