Description
The ICS2572 is a dual-PLL (phase-locked loop) clock gener-
ator 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.
A unique feature of the ICS2572 is the ability to redefine
frequency selections after power-up. This permits complete
set-up of the frequency table upon system initialization.
Features
