General Description

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 ±100ppm range.

Features

• 3.3V operating voltage

• Uses inexpensive pullable crystal

• 12mA drive capability at TTL levels

• On-chip oscillator with 200 ppm pull

range (±100 ppm)

• 8 pin SOIC package

Applications

• Set-top boxes

• Telecom switching

• Oscillator replacement

• MPEG Video clock source
