Video multiplexer boosts bandwidth

Edited by the Electronicstalk editorial team Nov 23, 2006

Multiplexer has bandwidth capable of exceeding the high-resolution requirements for high-definition (HD), 1080p and 1080i, and PC graphics video signals.

Fairchild Semiconductor introduces the FHP3194, the industry's first 1.2GHz 4:1 analogue multiplexer.

Boasting an 800MHz small-signal and 500MHz large-signal -3dB bandwidth (at G=2), the FHP3194 offers approximately 25% higher bandwidth than comparable devices.

This performance makes it the only multiplexer on the market today with the bandwidth capable of exceeding the high-resolution requirements for high-definition (HD), 1080p and 1080i, and PC graphics video signals.

With 0.1dB gain flatness to 90MHz at 2V peak-peak, it also ensures predictable performance in high-frequency designs.

This multiplexer offers designers the highest performing and most reliable solution for switching and driving high-speed video applications, including HDTVs, test and medical equipment, security systems and many other high-frequency products that require multiple I/O switching.

"Fairchild's FHP3194 offers designers the best option available for high-speed video applications", said Debbie Brandenburg, Marketing Engineer for Signal Conditioning Products, Fairchild Semiconductor.

"At the high PC graphics signal range our device exhibits 0.1dB gain flatness while competitive devices are 'peaking' and its constant gain allows the signal to pass more predictably, even when board layout is less than optimal".

"The result is easier, more flexible designs and more reliable end-systems".

"The FHP3194 is the latest example of Fairchild's commitment to providing leading-edge analogue products that enable HD video applications".

Other key features of the FHS3194 include: high (2200V/us) slew rate for optimal pulse response; disable/shutdown options and single 5V supply capability for power savings; and high (+/-75mA) output current for driving dual-video loads.

The FHP3194 is available in either a TSSOP-14 or an SOIC-14 package.

This lead (Pb)-free device meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with European Union regulations now in effect.
