ICS1522 - User-Programmable Video Clock Generator/ Line-Locked Clock Regenerator

General Description

The ICS1522 is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer.

Utilizing ICS’s advanced CMOS mixed-mode technology, the ICS1522 provides a low-cost solution for high-end video clock generation where synchronization to an external video source is required.

Key Features

  • Serial programming: Feedback and reference divisors, VCO gain, phase comparator gain, relative phase and test modes. Supports high-resolution graphics - Differential CLK out-puts to 230 MHz Eliminates need for multiple ECL output voltage controlled crystal oscillators and external components Fully-programmable synthesizer capability - not just a clock multiplier Line-locked clock generation capability; 15 - 100 kHz External feedback loop capability allows graphics system to be used as.

Integrated Circuit Systems, Inc. ICS1522 User-ProgrammableVideo Clock Generator/ Line-Locked Clock Regenerator General Description The ICS1522 is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer. Utilizing ICS’s advanced CMOS mixed-mode technology, the ICS1522 provides a low-cost solution for high-end video clock generation where synchronization to an external video source is required. The ICS1522 has differential video clock outputs (CLK+ and CLK- ) that are compatible with industry standard video DAC. Operating frequencies are fully programmable with direct control provided for reference divider, feedback divider and postscaler. Features • Serial programming: Feedback and reference divisors, VCO gain, phase comparator gain, relative phase and test modes.
