Intersil Introduces World's First 1 GHz RGB Muxes
-- Only Muxes That Handle Any Existing Resolution on the Market
MILPITAS, CA, January 31, 2006 Intersil Corporation, a world leader in the design and manufacture of high-performance analog solutions, today announced the ISL59445 and ISL59424, two quad RGB (red, green, blue) or YPbPr (the color space used in video electronics) multiplexers with 1 GHz of bandwidth. These devices are accompanied by a complete family of nearly 1 GHz multiplexers for RGB and high-speed analog applications. The ISL59445 and ISL59424 are 1GHz bandwidth multiplexing amplifiers designed primarily for video input switching.
These MUX-amps exhibit a fixed gain of 1 and also 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 (EN) pin, when pulled high, sets the ISL59424 and ISL59445 to low-current mode, consuming just 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.
Intersils ISL5944xx family extends the available bandwidth of RGB multiplexers on the market from 500 MHz (Intersils EL4342) up to 1 GHz the first time this barrier has been broken, said Simon Prutton, VP/GM of Intersils Analog & Mixed Signal Products Group. We will continue to deliver best-in- class video solutions for our customers, taking into consideration every piece of the signal chain. This family of ultra high-speed devices allows customers to not worry about the resolution of their source as these devices can handle all existing sources. When combined with Intersils 1 GHz triple amplifier (EL5367) and QXGA-capable video digitizer (ISL98001-275), we provide a unique, solution thats unfettered by bandwidth constraints, for high-resolution displays.
