Block Diagram
Dual Programmable Graphics Frequency Generator
The ICS9161A is a fully programmable graphics clock
generator. It can generate user-specified clock
frequencies using an externally generated input
reference or a single crystal. The output frequency is
programmed by entering a 24-bit digital word through
the serial port.Two fully user-programmable phase-
locked loops are offered in a single package. One PLL
is designed to drive the memory clock, while the
second drives the video clock. The outputs may be
changed on-the-fly to any desired frequency between
390 kHz and 120 MHz. The ICS9161A is ideally suited
for any design where multiple or varying frequencies
are required.
This part is ideal for graphics applications. It generates
low jitter, high speed pixel clocks. It can be used to replace
multiple, expensive high speed crystal oscillators. The
flexibility of the device allows it to generate non-standard
graphics clocks.
The ICS9161A is also ideal in disk drives. It can generate
zone clocks for constant density recording schemes. The low
profile, 16-pin SOIC or PDIP package and low jitter outputs
are especially attractive in board space critical disk drives.
The leader in the area of multiple output clocks on a single
chip, ICS has been shipping graphics frequency generators
since October, 1990, and is constantly improving the
phase-locked loop.The ICS9161A incorporates a patented
fourth generation PLL that offers the best jitter performance
available.
