VT73227
VCXO
(Voltage-Controlled Crystal Oscillator)
27 MHz 3.3V
Applications
•= Set-top boxes
•= Telecom switching
•= Oscillator replacement
•= MPEG Video clock source
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
