General Description

The Vaishali VT73127 is a single-chip, low-jitter Voltage-Controlled-Crystal-Oscillator. The device accepts a 27 MHz, 20 pF crystal input, and produces a low jitter output at the same frequency. The output is enabled when OE is logic HIGH and goes into high impedance state when OE is logic LOW. 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 crystals

• 12mA drive capability at TTL levels

• On-chip oscillator with 200 ppm pull range (±100 ppm)

• Active High output enable

• Die only

Applications

• Crystal-driven clock source
