Product Details

Description



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 the feedback divisor with synchronous switchover to internal feedback
• Small footprint 24-pin SOIC
• Coarse and fine phase adjustment permits precise clocking in video recovery application


Application

• LCD Projector Systems
• Multimedia video line locking
• Genlock applications

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
