PLL Clock Generator IC with VCXO
April 2000
1.0 Features
• Phase-locked loop (PLL) device synthesizes output
clock frequency from crystal oscillator or external ref-
erence clock
• On-chip tunable voltage-controlled crystal oscillator
(VCXO) allows precise system frequency tuning
• Typically used for generation of MPEG-2 decoder
clock
• 3.3V supply voltage
• Very low phase noise PLL
• Use with “pullable” 14pF crystals – no external pad-
ding capacitors required
• Small circuit board footprint (8-pin 0.150″ SOIC)
• Custom frequency selections available - contact your
local AMI Sales Representative for more information
2.0 Description
The FS6128 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6128 is circuitry that implements a
voltage-controlled crystal oscillator (VCXO) when an ex-
ternal resonator (nominally 13.5MHz) is attached. The
VCXO allows device frequencies to be precisely adjusted
for use in systems that have frequency matching re-
quirements, such as digital satellite receivers.
A high-resolution phase-locked loop generates an output
clock (CLK) through a post-divider. The CLK frequency is
ratiometrically derived from the VCXO frequency. The
locking of the CLK frequency to other system reference
frequencies can eliminate unpredictable artifacts in video
systems and reduce electromagnetic interference (EMI)
due to frequency harmonic stacking.
