ICS614-01
16 pin Intel Graphics Clock Source
Description
Features
The ICS614-01 is a low cost, low jitter, high
performance clock synthesizer for Intel’s i752
graphics systems. It includes frequencies for video
encoders and decoders. Using analog Phase-
Locked Loop (PLL) techniques, the device accepts
a 27 MHz fundamental mode crystal or clock
input to produce multiple output clocks. The chip
provides highly accurate video encoder and
decoder clocks, as well as the 48 MHz necessary
for the Intel graphics processor, and can produce a
24.576 MHz audio clock.
• Packaged in 16 pin SOIC
• Uses fundamental 27 MHz input crystal
• Supports Intel i752 graphics chip, popular video
encoders and decoders, and audio
• Low jitter - 50 ps one sigma
• Output Enable function tri-states outputs
• 25mA output drive capability at TTL levels
• Advanced, low power, sub-micron CMOS process
• 5V±10% core voltage. Inputs and outputs can run
3.3V (or 5V) for easy system interface
See the ICS604 or ICS513 for 8 pin devices that
supply 48 MHz from a 14.31818 MHz input.

PRELIMINARY INFORMATION
ICS614-01
16 pin Intel Graphics Clock Source
External Components/Crystal Selection
The ICS614-01 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.01 µF should be connected between VDD and GND, one between pins 4 and 5, and one
between pins 13 and 12, as close to the part as possible. A series termination resistor of 33 Wmay be used
for each clock output. The 27.000 MHz crystal must be connected as close to the chip as possible. The
crystal should be a fundamental mode, parallel resonant, 30 ppm or better. Do not use third overtone.
Crystal capacitors should be connected from pins X1 to ground and X2 to ground. In general, the value of
these capacitors is given by the following equation, where C is the crystal load capacitance: Crystal caps
L
(pF) = (C -6) x 2. So for a crystal with 16 pF load capacitance, two 20 pF caps can be used. For any given
L
board layout, ICS can measure the board capacitance and recommend the exact capacitance value to use.
