ICS1567
Differential Output Video Dot Clock Generator
General Description
The ICS1567 is a very high performance monolithic PLL
frequency synthesizer. Utilizing ICS’s advanced CMOS
mixed-mode technology, the ICS1567 provides a low cost
solution for high-end video clock generation, and for telecom
system clock generation.
The ICS1567 has differential video clock outputs (CLK and
CLK) that are compatible with industry standard video DACs
& RAMDACs. An additional clock output, LD, is provided,
whose frequency is divided down from the main clock by a
programmable divider.
Operating frequencies are selectable from a pre-programmed
(customer-defined) table. An on-chip crystal oscillator for gen-
erating the reference frequency is provided on the ICS1567.
Programming of the ICS1567 is accomplished via frequency
select pins on the package. The ICS1567 has five lines plus a
STROBE pin which permits selection of 32 frequencies. Reset
of the pipeline delay on Brooktree RAMDACs is automatically
performed on a rising edge of the STROBE line.
Features
High frequency operation for extended video modes - up
to 180 MHz
Compatible with Brooktree high performance RAMDACs
a)
Differential output clocks with ECL logic levels
b) Programmable divider modulus for load clock
c)
Circuitry included for automatic reset of Brooktree
RAMDAC pipeline delay

oscillators in video display systems
Strobed/Transparent frequency select options
32-user selected mask-programmable frequencies
Fast acquisition of selected frequencies, strobed or non-
strobed
Advanced PLL for low phase-jitter
Dynamic control of VCO sensitivity providing optimized
loop gain over entire frequency range
