Royal Philips Electronics recently unveiled a multi-standard hybrid silicon tuner IC capable of receiving both analog and digital terrestrial broadcasts.

According to the company, the TDA18271HD tuner chip offers fast time-to-market, space savings, HD picture quality and significant cost advantages. It promises to deliver a field-proven, production ready reference design; reduce bill-of-materials by up to 25 percent; and meet CENELEC and Nordig specifications. Touted to be significantly smaller than traditional can tuners, this device has a power consumption of less than 800mW.

Philips said they were able to achieve this by being the first to provide an integrated splitter and feed-through in its silicon tuners that make it easy to chain them in multi-tuner systems. This step alone brings significant cost savings compared to any existing multi-tuner solutions, added the company.

"In the past, PC makers had to use bulky can tuners to reach high performance reception, high picture quality and low power consumption", said Robert Murray, marketing director for TV front end solutions at Philips. "Today our considerably smaller hybrid silicon tuner reaches the same performance while significantly reducing systems costs. Our production ready reference designs pass both Nordig Unified and CENELEC and make sure that customers will get their new PVR capable products quicker into the homes of the consumers at an affordable price."

The TDA18271HD silicon tuner, combined with a channel decoder (TDA10048) and a video-decoder (SAA713x), provides a full system for PCTV hybrid terrestrial applications at low power consumption. The integration of the analog IF demodulator in video decoders reduces the overall system size and cost, while lowering the cost of DTV only systems, explained Philips.

Within the TDA18271HD are RF tracking filters for unwanted signal suppression, IF selectivity and RF output for easy implementation in PVR dual tuner based cards. Features such as multi-tuner configuration and loop-through for easy chaining of tuners were designed based on the input of leading manufacturers. The TDA18271HD offers 60dB image rejection, 5dB noise figure and a power consumption of 780mW.

Samples of the TDA18271HD are already available. Production quantities are expected for Q3 2006. Per unit pricing is less than $5 for quantities of 10,000 units.
