Silicon tuner eases HD multi-tuner STB design

NXP Semiconductors debuts a dual silicon tuner for cable TV applications that simplifies the design of HD multi-tuner cable STBs and enables up to six channels with high performance on each stream.

The TDA18260 tuner IC eliminates tuner-to-tuner interference as well as the need to add complex, costly RF components such as low-noise amplifiers, splitters, SAW filters and incremental crystal oscillators.

The TDA18260 benefits cable operators by reducing the overall cost, size, and power consumption of feature-rich STBs or gateways, even as the number of tuners per STB increases due to growing demand for services such as watch and record, video on demand, and high-speed Internet. The TDA18260 will also allow handling of multiple streams of HD 3D TV.

The device features an integrated splitter that eases and simplifies the design of dual tuner PVRs and interfaces directly to an SoC that includes cable demodulators. Thus, where an STB design calls for external demodulators, NXP provides a very small, cost-effective system solution in a companion dual demodulator, the TDA10025.

NXP claims to be the only silicon tuner manufacturer offering high-performance dual silicon tuners for both cable and satellite STB applications.

The TDA18260 dual silicon tuner for cable TV applications has entered volume production and is available immediately.
