Intersil Corp. unveiled the ISL59445 and ISL59424, two quad RGB (red, green, blue) or YPbPr (the color space used in video electronics) multiplexers with 1GHz of bandwidth. According to the company, these new devices are accompanied by a complete family of nearly 1GHz multiplexers for RGB and high-speed analog applications.

The ISL59445 and ISL59424 MUX-amps exhibit a fixed gain of 1, and feature high-speed tri-state outputs to enable the output of multiple devices to be wired together. All logic inputs have pull-downs to ground and may be left floating. The enable pin, when pulled high, sets the ISL59424 and ISL59445 to low-current mode, consuming 15mW. An added feature in the ISL59424 is a latch enable (LE) function that allows independent logic control using a common logic bus. When LE is high, the last logic state is preserved.

"The ISL5944xx family extends the available bandwidth of RGB multiplexers on the market from 500MHz up to 1GHzthe first time this barrier has been broken," said Sameer Vuyyuru, director of high-speed analog for Intersil. "When combined with the EL5367 1GHz triple amplifier and ISL98001-275 QXGA-capable video digitizer, we provide a unique, solution that's unfettered by bandwidth constraints for high-resolution displays."

The ISL59424 is available in a 24-lead QFN package and is priced at $4.11, while the ISL59445 is housed in a 32-lead QFN package and is priced at $5.20. Both prices are for 1,000-unit quantities.
