General Description
The Vaishali VT83027 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 13.5 MHz, 14 pF (pull range of 200 ppm) crystal input, and produce a 27 MHz output. A 0 to 3V control signal is used to fine tune the output clock frequency in the ±100ppm range.
