Dual Programmable Graphics Frequency Generator
9161-A RevG 10/04/00
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.
