The VC5035 oscillator IC series operate from 1.6~3.6 volts over a range of 70 MHz to 165 MHz (1.8V) and 70 MHz to 220 MHz (2.5 to 3.3V) for both 3rd overtone oscillation and fundamental oscillation modes. Fabricated on a proprietary BiCMOS process, the VC5035 combines a bipolar Colpitts oscillator with integrated passives that provide stable operation and excellent startup with CMOS output buffers that will operate at high frequencies with a 15pF capacitance load. A unique circuit inhibits output until it detects proper oscillation, providing for excellent cold-first-cycle startup response. The operating temperature range is 55°C to 125°C.
