Telegent Debuts Single-chip DVB-T + Analog TV Receiver

Telegent Systems, a start-up based in Sunnyvale, California, introduced a single-chip CMOS hybrid TV receiver for enabling free-to-air TV on personal computers (PCs), laptops, netbooks and other portable devices.

Telegent's new TLG2300 chip supports digital (DVB-T) and analog (PAL/SECAM/NTSC) TV and FM radio, enabling it to be used in markets across the world. In countries transitioning to DVB-T, the TLG2300 combines the benefits of digital TV with the ubiquitous availability of analog, ensuring live TV reception regardless of digital deployment. Support for analog standards extends target markets to countries where there is no imminent digital conversion, which accounts for more than 85% of the world's population through 2012.

Telegent estimates that its TLG2300 reduces power demand by 75%, size by 50% and TV feature cost by 60% relative to existing solutions while delivering industry-leading video sensitivity and picture quality with margin to key NorDig specifications. The thermal profile will enable it to be embedded into laptops and netbooks.

The TLG2300 integrates the RF tuner, demodulator, decoder, audio/video processing, FM stereo radio, and USB 2.0 interface in less than 4.25 cm2 of board space enabling a single-sided, four-layer, half-mini PCIe form factor. Sampling is underway.

"With the technical innovation delivered by the TLG2300, live TV can now become a standard feature in PCs, laptops and other portable devices" said Weijie Yun, president and CEO of Telegent Systems. "TV is a particularly intuitive feature for media-centric devices such as netbooks and MIDs that allows manufacturers to differentiate their products and penetrate non-digital and emerging markets where analog support is required."

  • Telegent Systems was co-founded in 2004 by
    Weijie Yun (CEO) and Samuel Sheng (CTO). Prior to Telegent, Yun led marketing and product management at Berkana Wireless, which developed a single-chip RF CMOS receiver for GSM/GPRS cellular applications. He also served as the founding president & CEO of AIP Networks and was a founder and director of SiTek. Prior to co-founding Telegent Systems, Sam Sheng was at LSI Logic and was responsible for architecting and implementing a series of silicon RF tuners for video-band applications, targeted for cable modems, analog/digital video over cable, and voice over IP as well as highly integrated DVD front-end technologies. Before LSI Logic, Sam co-led the ADSL front-end (AFE) development effort at Datapath Systems.
