General Description
The Vaishali VT83205 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 14.318 MHz, 30pF (pull range of 200 ppm) crystal input, in order to produce either one or two output clocks.
