Low-Cost Digital-to-Analog Converter from Harris Semiconductor Couples High Performance with Low Power

— New 10-bit, 125MSPS D/A Converter delivers multiplexed input for LCD applications

MELBOURNE, FL, March 8, 1999 — Harris Semiconductor today announced a new digital to analog (D/A) converter specifically designed for use in LCD projectors, LCD in flat-panel monitors, Plasma Displays and High Definition Television (HDTV) applications.

The HI3197 is a high-speed D/A converter that can perform the Digital-to-Analog conversion using multiplexed input 10-bit data. It features a mixed input that interfaces directly with the 48-bit output of most image scalers, and delivers a maximum conversion rate of 125MSPS.

The multiplexed operation is possible by the ½ frequency-divided clock or by halving the frequency of the clock with the clock frequency divider circuit.

The HI3197 has low power consumption (400mW typ.), Low Glitch Energy and can operate with single or dual power supplies.

Price and Availability
Packaged in 48-lead MQFP, the HI3197 is available from stock for $8.80 in quantities of 100s.

Harris Signal Processing Focus
The HI3197 is an example of Harris Semiconductor's company-wide focus on high-speed signal processing as applied to communication applications. The Harris D/A converter line covers the resolution scale from 8- to 14-bits and from 20 to 160MSPS. In addition to data converters, Harris addresses the entire signal processing chain with a portfolio of linear, mixed-signal, DSP ICs optimized for high-speed and multimedia application-specific products. End-markets include video and image processing, high-speed communications, and test and measurement equipment.
