ABV0251
Low Phase Noise VCXO (20MHz to 52MHz)
30332 Esperanza., Rancho Santa Margarita, Ca 92688 Ph: 949-546-8000 Fax: 949-546-8001 www.Abracon.com 03/21/05 Page 1
FEATURES
Integrated voltage-controlled crystal oscillator
circuitry (VCXO) (pull range 380ppm minimum).
VCXO tuning range: 0V - VDDV.
Uses inexpensive fundamental-mode parallel
resonant crystals (from 20 to 52MHz).
2.5V or 3.3V supply voltage.
Selectable High Drive (30mA) or Standard Drive
(10mA) CMOS output.
Available in 8-Pin SOIC or TSSOP.
DESCRIPTION
The ABV0251 is a monolithic low jitter, high per-
formance CMOS VCXO IC. It allows control of the
output frequency with an input voltage (VCON), us-
ing a low cost crystal.
This makes the ABV0251 ideal for a wide range of
applications from 20MHz to 52MHz (including
27MHz, 35.328MHz, etc.).
