Analog devices intros signal splitter for set-top boxes


The Analog Devices ADA4302-4 active RF splitter offers a lower noise level and better composite second order distortion.
Analog Devices has introduced an active RF splitter IC that uses four-way signal-splitting technology to resolve design challenges in multi-tuner cable set-top boxes (STBs) and advanced televisions.

The ADA4302-4 delivers video or data content to multiple applications simultaneously, enabling features such as picture-in-picture capability and personal video recording. By dividing an input into four outputs without degrading the signal quality, the device enables low noise and distortion, while reducing design work and overall system cost.

The lower noise and distortion levels allow systems to be sensitive to smaller signals, resulting in fewer signal interruptions and clearer pictures. The splitter has 2dB lower noise figure and 16dB better composite second order distortion (CSO), all within a compact (4mm x 4mm), single-chip solution.

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, said Curt Ventola, product line director, Analog Devices. An STB equipped with an 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.

The ADA4302-4 is available in a 4mm x 4mm lead frame chip-scale package (LFCSP).
