General Description
The Vaishali VT83201 is a single-chip, integrated VCXO and Phase Locked Loop (PLL) clock synthesizer.
The device uses the VCXO and an analog Phase-Locked Loop (PLL) to accept a 10 MHz to 20 MHz, 30pF
(pull range of 200 ppm) crystal input, in order to produce either one or two output clocks. A 0 to 3V control
signal is used to fine tune the output clock frequency in the ±100ppm range. Select inputs S0 and S1 are
used for frequency and output selection.
