Fairchild Semiconductor has introduced the FHP3194, a 1.2GHz 4:1 analog multiplexer. Boasting an 800MHz small-signal and 500MHz large-signal -3dB bandwidth (at G=2), the FHP3194 offers approximately 25 percent 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 graphic video signals.

With 0.1dB gain flatness to 90MHz at 2Vpp, 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 analog products that enable HD video applications.”

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.
