VT73227 - VCXO (Voltage-Controlled Crystal Oscillator) 27 MHz 3.3V
The Vaishali VT73227 is a single-chip, low-jitter Voltage-Controlled-Crystal-Oscillator.
The device accepts a 27 MHz, 20 pF (pull range of 200 ppm) crystal input, and produces a low jitter output at the same frequency.
A 0 to 3.0V control signal is used to fine tune the output clock frequency in the
