Description

CH9294 is a dual PLL clock generator designed for high frequency graphics applications. It can also be used in applications requiring multiple clocks, such as PC motherboards, disk drives, CD-ROM systems, and modems.

Features

• Generates 16 preset video clocks, 8 preset memory clocks, and buffers the reference frequency output

• Built-in power supply conditioning circuitry provides excellent jitter performance and eliminates the need for an external VDD dropping resistor

• Requires only two external components: one 14.318 MHz crystal and one 0.1 µF decoupling capacitor

• Supports VGA, Super-VGA, XGA™, and 8514 graphic standards

• Supports output frequencies up to 135 MHz

• Drop-in replacement for ICS2494 and AV9194

• CMOS technology in 20-pin PDIP and SOIC

• 5V or 3.3V supply. For specific details on the 3.3V version, please consult Chrontel.
