ICS1567M Datasheet PDF - Integrated Circuit Systems

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.

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
• Low cost - eliminates need for multiple ECL crystal clock oscillators in video display systems
• Strobed/Transparent frequency select options
• 32-user selected mask-programmable frequencies
• Fast acquisition of selected frequencies, strobed or nonstrobed
• Advanced PLL for low phase-jitter
• Dynamic control of VCO sensitivity providing optimized loop gain over entire frequency range
• Small footprint - 16-pin wide body (300 mil) SOIC

APPLICATIONs
• Workstations
• High-resolution PC and MAC displays
• 8514A - TMS340X0 systems
• EGA - VGA - Super VGA video
• Telecom reference clock generation - suitable for Sonet, ATM and other data rates up to 155.52Mb.
