VL-821-EAW-KA

VL-821 CMOS Crystal Oscillator Previous Vectron Model VCS3 VL-821 Description Vectron’s VL-821 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, or 3.3 volt supply. The VL-821 utilizes a high performance, low frequency quartz resonator followed by a custom ASIC to synthesize the output frequency.
