FS6132
VCXO Clock Generator IC
April 2000
1.0 Features
• On-chip tunable voltage-controlled crystal oscillator
circuitry (VCXO) allows precise system frequency
tuning (pull range typically +/-150 ppm)
• VCXO tuning range: 0-3V
• Uses inexpensive fundamental-mode crystals
• Integrated phase-locked loop (PLL) multiplies VCXO
frequency to the higher system frequencies needed
• 5V core supply voltage (contact factory for 3.3V)
• 3.3V / 5V output supply voltage
• Small circuit board footprint
16-pin 5.3mm (0.209”) SSOP
• Custom frequency selections available - contact your
local AMI Sales Representative for more information

2.0 Description
The FS6132 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6132 is circuitry that implements a
voltage-controlled crystal oscillator when an external
resonator is attached. The VCXO allows device frequen-
cies to be precisely adjusted for use in systems that have
frequency matching requirements, such as digital satellite
receivers.
A high-resolution phase-locked loop generates the output
clock frequencies (CLKA and CLKB). These frequencies
are phase-locked and frequency-locked to the VCXO fre-
quency.
