TV tuner chip packages three types in one

22 March 2006 Telecoms, Datacoms, Wireless, IoT

Microtune has unveiled a breakthrough three-in-one TV tuner engineered to drive very high-end digital TV reception quality into the cost-sensitive consumer TV mass market. Integrating three tuners - analog, digital and cable - in a chip smaller than a drawing-pin, the MicroTuner MT2131 tuner complies with all three existing US TV requirements: ATSC, NTSC and digital cable ready (DCR). Eliminating more than 100 components from the silicon tuner bill of materials (BOM), the company claims the MT2131 cuts external BOM cost by 60%. The MT2131 is also engineered to solve each of the three technical problems commonly identified by consumers as sources of DTV dissatisfaction: TV picture break-up from interference, TV picture freezing and TV picture loss. The single-chip device in 7 x 7 mm 48 pin QFN package receives frequencies in the full 48 MHz to 1,0 GHz range and converts a selected channel to a standard IF between 30 and 57 MHz. It incorporates several critical RF components on chip, including: variable gain low noise amplifier; closed-loop AGC RF gain control; integrated broadband power detectors; variable gain IF amplifier; Microtune's ClearTune filter, and FDC path for DCR applications. Further, it offers a single-ended input to eliminate an expensive external transformer balun.
