Analog Devices Debuts Four-Way Splitter

Analog Devices Inc. Tuesday introduced its “ADA4302-4” active RF splitter integrated circuit that uses four-way signal-splitting technology.

The vendor said the four-way splitting helps to resolve design challenges in multituner set-tops and advanced televisions that need to simultaneously deliver video or data content to multiple applications, enabling features such as picture-in-picture and personal video recording.

By dividing an input into four outputs without degrading signal quality, the device enables the lowest noise and distortion, while reducing design work and overall system cost, Analog Devices said.

"For cable set-top-box manufacturers to achieve functionality beyond just receiving and decoding digital-broadcast signals, RF-system designers require advanced signal-splitting technology," Analog Devices product-line director Curt Ventola said in a prepared statement.

“A set-top box equipped with Analog Devices' ADA4302-4 can receive one incoming signal and divide and deliver it to four tuners, or three tuners and a cable modem, enabling a consumer to simultaneously view one televised program, set a digital-video recorder for recording another program, use a cable modem to access the Internet and run picture-in-picture settings,” he added.
