ICS662-02
NTSC/PAL AUDIO CLOCK
Description
The ICS662-02 is a low cost, low jitter, high
www.daptaesrhfoeermt4ua.ncocme PLL clock synthesizer designed to
replace oscillators and PLL circuits in set-top box and
multimedia systems. Using ICS’ patented analog
Phase Locked Loop (PLL) techniques, the device uses
a NTSC/PAL reference clock input to produce a
selectable audio clock.
ICS manufactures the largest variety of Set-Top Box
and multimedia clock synthesizers for all applications.
Consult ICS to eliminate VCXOs, crystals and
oscillators from your board.
Features
Packaged in 8 pin SOIC
Locks to NTSC and PAL colorburst frequencies (4x)
Audio sampling rate outputs
Low synthesis error in all clocks
All frequencies are frequency locked
Advanced, low power, sub-micron CMOS process
Operating voltage of 3.3 V

External Components
Decoupling Capacitor
As with any high performance mixed-signal IC, the
www.daItCasSh6ee6t24u-0.c2ommust be isolated from system power supply
noise to perform optimally.
A decoupling capacitor of 0.01µF must be connected
between VDD and GND on pins 2 and 3. It must be
connected close to the ICS662-02 to minimize lead
inductance. No external power supply filtering is
required for the ICS662-02.
Series Termination Resistor
A 33W terminating resistor can be used next to the
clock outputs for trace lengths over one inch.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS662-02. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
