Royal Philips has introduced a small, low-power DVB-T/H channel decoder, the TDA10048HN. Combined with the latest generation silicon tuners, the TDA18211/18271HD, Philips said the new decoder is a very compact digital TV front-end. For manufacturers, this will allow production of a cost-effective, rapidly integrated product, the company said, which can be used in any home entertainment deviceSTBs, DVD recorders, iDTV, portable media players or multituner products such as personal video recorders.

The device is also a coded orthogonal frequency-division multiplexing demodulator able to operate with power consumption as low as 160mW, according to Philips, reducing power bills from STBs and providing longer use time for battery powered applications. The DVB-T/H channel decoder is fully compliant with European demodulation standards, including the latest Nordig unified and D-Book specifications.

"Devices offering low power consumption and easy integration will drive adoption of future digital home products," said Menno Kleingeld, senior marketing director, Philips Semiconductors. "The DVB-T/H channel decoder not only delivers the most effective power efficiency in its class, it enhances user experience by ensuring reliable TV reception, speedy channel surfing and longer playback on portable digital TV devices. Production-ready reference designs from Philips ensure a quick time-to-market and built-in functionality reduces BOM for manufacturers."

The TDA10048HN supports DVB-T 2K, 4K and 8K FFT length and is also capable of demodulating any DVB-H transmissions for portable applications. The IC includes adjacent and co-channel rejection capability with on-chip digital filters, adaptive echo cancellation with Doppler compensation, ultrafast channel scanning and an enhanced "pulse killer" algorithm that reduces the disturbing effects caused by impulsive noise interference from vehicle, personal computers, phones and other domestic electrical appliances, Philips explained.

Packaged in a 7-by-7mm 48-pin HVQFN casing, the TDA10048HN has a pad pitch of 0.5mm, which enables the use of ultracompact, low-cost PCBs. The device is available on evaluation boards with drivers as well as production-ready reference designs for STBs, multituner products and portable TV applications to enable OEMs achieve a rapid time-to-market at low costs.

Samples of the TDA10048HN are already available. Volume production will begin in Q3 2006.
