NXP Announces Dual Silicon Tuner for Cable

NXP Semiconductors N.V. has announced that TDA18260, a dual silicon tuner for cable set-top boxes (STBs), is now in volume production and available immediately. The TDA18260 simplifies the design of high-definition multi-tuner cable STBs, enabling up to six channels with high performance on each stream. The dual cable silicon tuner IC from NXP eliminates tuner-to-tuner interference as well as the need to add complex, costly RF components such as lownoise amplifiers, splitters, Surface Acoustic Wave (SAW) filters and incremental crystal oscillators.

The introduction of the TDA18260 benefits cable operators by reducing the overall cost, size, and power consumption of feature-rich set-top boxes 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 highspeed Internet. The TDA18260 will also allow handling of multiple streams of HD 3DTV.

The TDA18260 directly interfaces to a System on Chip (SoC) that includes cable demodulators. Where a set-top box design calls for external demodulators, NXP provides a very small, cost-effective system solution in a companion dual demodulator, the TDA10025.
