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

• 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
