Description
The ICS2572 is a dual-PLL (phase-locked loop) clock generator with differential video outputs specifically designed for high-resolution, high-refresh rate, video applications. The video PLL generates any of 16 pre-programmed frequencies through selection of the address lines FS0-FS3. Similarly, the auxiliary PLL can generate any one of four pre-programmed frequencies via the MS0 & MS1 lines.

Features
• Advanced ICS monolithic phase-locked loop technology
• Supports high-resolution graphics - differential CLK output to 185 MHz
• Divided dotclock output (LOAD) available
• Simplified device programming
• Sixteen selectable VCLK frequencies (all user re-programmable)
• Four selectable MCLK frequencies (all user re-programmable)
• Windows NT compatible

Applications
• High end PC/low end workstation graphics designs requiring differential output
• X Terminal graphics
