TC90541:OFDM Demodulation and Error Correction IC for ISDB-T One-Segment Receivers
Fabricated using Toshiba's proprietary RFCMOS process, the TC90541 combines an RF tuner with an OFDM demodulation and error correction on a single chip. The TC90541 is specifically designed for ISDB-T one-segment receiver applications and conforms to ARIB STD-B31, a terrestrial digital television broadcasting standard.
The integrated unique interference detection unit allows the TC90541 to avoid radio waves that could interfere with ISDB-T reception, such as regular terrestrial TV waves. This allows for precise tuning of a desired frequency, which improves reception sensitivity and reduces power consumption. The TC90541 is offered in two types of packages to address a variety of needs for mobile devices: a standard WCSP suitable for on-board assembly and a thin WCSP that fits into a small tuner module.
