Infineon Technologies AG unveiled the high performance, low power tuner ICs TUA6041 and TUA6045 designed for portable applications such as laptops, USB dongles and PDAs. Both ICs are claimed to be the industry's first single conversion tuners operating at a supply voltage as low as 3V, halving their power consumption and heat dissipation. To meet the increasing space constraints of portable end-user devices, added Infineon, the TUA6041 and TUA6045 integrate the radio frequency (RF) and intermediate frequency (IF) functions in one chip, improving system reliability and decreasing the footprint area of the tuner IC by around 50 percent to 49mm2.

According to Giuseppe Calarco, GM of the tuner systems business unit at Infineon's communication business group, the new tuner ICs fulfill the requirements of portable television receivers with regards to footprint, performance and low power consumption. "Eight out of ten of the world's 12 million TV sets and STBs for terrestrial digital television already operate with components from Infineon. We are committed to leverage this expertise and to offer our customers leading edge tuner solutions that enable a broad range of portable and mobile applications," Calarco added.

Operating at a supply voltage from 3V to 5.5V, the new tuner ICs promise to allow manufacturers of tuners and end-user equipment to adjust the tuner IC according to the system's power requirements. Power consumption of the end-user equipment is further reduced thanks to the stand-by mode function of the tuner IC while a selectable narrow or wide band Automatic Gain Control improves the TV reception quality, said Infineon. In addition to manual alignment, the TUA6041 features automatic digital alignment by the means of software during basic set-up in the production process.

Both the TUA6041 and TUA6045 devices address multiple analog and digital TV standards (PAL, SECAM, NTSC, DVB-C, DVB-T, T-DMB, DAB, ISDB-T and ATSC).

Samples of the TUA6041 and TUA6045 are already available, with volume production planned for the end of 2005. Live demonstrations of these new tuner ICs are being held at the China Digital Consumer Electronics Component Exhibition in Shanghai (Nov. 22-25).
