Overview
VCA3 series 3.
3, 5.
0 volt CMOS Oscillator Features • CMOS output • Output frequencies to 160 MHz • Tri-state output for board test and debug • 0/70 or –40/85 °C operating temperature • Product is compliant to RoHS directive and fully compatible with lead free assembly The VCA3 Crystal Oscillator Applications • SONET/SDH/DWDM • Ethernet, Gigabit Ethernet • Storage Area Network • Digital Video • Broadband Access fo Output Buffer / Disable • Microprocessors/DSP/FPGA Description Vectron’s VCA3 Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off a 3.
3 or 5.
0 volt supply.
The VCA3 uses fundamental or 3rd overtone crystals, for output frequencies < 80MHz, resulting in low jitter performance, typically 0.
5ps rms in the 12 kHz to 20MHz band.
