Dual-standard tuner enables broadcast, mobile digital TV on portable devices
May 2, Plano, TX -- Extending its family of ultra low-power tuners, Microtune recently introduced a dual-standard, dual-band tuner chip that receives and tunes both digital terrestrial TV and mobile broadcast TV signals for portable applications. When implemented into consumer multimedia devices, the company says its Mobile MicroTuner MT2266 enables users to access broadcasts across the digital video broadcast-terrestrial (DVB-T) and digital video broadcast-handheld (DVB-H) standards.
May 2, Plano, TX -- Extending its family of ultra low-power tuners, Microtune recently introduced a dual-standard, dual-band tuner chip that receives and tunes both digital terrestrial TV and mobile broadcast TV signals for portable applications. When implemented into consumer multimedia devices, the company says its Mobile MicroTuner MT2266 enables users to access broadcasts across the digital video broadcast-terrestrial (DVB-T) and digital video broadcast-handheld (DVB-H) standards.
Measuring 6 x 6-mm in a 40-pin QFN package, the tuner contains all active circuitry required to implement a complete radio frequency (RF) to baseband function. As with other Microtune tuner products, the company says the MT2266 is characterized by a high level of integration that minimizes the need for external parts, including the requirement for an external low-noise amplifier, IF saw filters, and transformer balun. The company says this architecture reduces both total cost and total power budget, while supporting significantly reduced footprint designs in portable applications. According to the company, the MT2266 operates from a 2.7 V power supply and consumes as little as 350 mW, with multiple power down modes.
According to the company, with half the power consumption of conventional DVB-T tuners, the MT2266 has minimal impact on the battery life of portable platforms. The company says that original equipment and original design manufacturers can take advantage of the MT2266 tuner to deliver dual-standard TV capabilities and multimedia features on products as diverse as notebook PCs, USB sticks, PCI Express cards, portable DVB-T receivers, PDAs, and personal media players. The tuner, which supports both the UHF and VHF (Band III) frequency bands, is also suitable for diversity systems, where low power is a critical consideration. The device is engineered to deliver robust performance based on the NorDig Unified and MBRAI specifications.
Currently sampling with manufacturers, the MT2266 is expected to be in production this year. Reference designs are expected to be available in Q2 2006. The tuner is priced at $5.00 in quantities of 10,000.
