PLL501-03SI Overview

VCXO Clock Generator IC

PLL501-01/-03
VCXO Clock Generator IC
FEATURES
Integrated voltage-controlled crystal oscillator
circuitry (VCXO) (pull range 200ppm minimum).
Ideal for ADSL (35.328MHz) and Set-Top Box
and multimedia (27MHz) applications.
VCXO tuning range: 0-3.3V.
Uses inexpensive fundamental-mode parallel
resonant crystals (from 10 to 20MHz).
Integrated phase-locked loop (PLL) provides
pullable output frequency at 2x (PLL501-01) and
4x (PLL501-03) crystal frequency.
3.3V supply voltage.
Small circuit board footprint (8-pin 0.150’’ SOIC).
12mA output drives capability at TTL level.

DESCRIPTIONS
The PLL501-01 and PLL501-03 are monolithic low
jitter, high performance CMOS VCXO chips. They
allow the control of the output frequency with an
input voltage (VIN), using a low cost crystal.
While the PLL501-03 provides a pullable output
clock 4 times the input crystal frequency, the
PLL501-01 provides a pullable output clock 2x the
input crystal frequency. This makes the PLL501-01
ideal for 35.328MHz ADSL applications (using
17.664MHz crystal) and for 27MHz Set-Top Box /
multimedia applications (with a 13.5MHz crystal).
