NXP introduces DVB-T silicon tuner for SD/HD STBs

NXP has introduced its high-definition digital terrestrial silicon tuner, the TDA18211HD, which raises the performance and lowers the costs of set-top box applications. The TDA18211HD is the industry's first pure DVB-T Silicon Tuner, eliminating the need for an external SAW filter and only requiring one XTAL for a full Dual/PVR DVB-T front-end solution.

The TDA18211HD offers multi-tuner configuration, easy on-board integration and reduces tuner function size, affording manufacturers the ability to achieve smaller form factor devices. It features fully integrated RF tracking filters, wholly incorporated IF selectivity, an RF loop-through for easy STB implementation, fully integrated oscillators, built-in wideband gain control, a 16MHz XTAL output buffer for single crystal applications, an I2C interface compatible with 3.3V and 5V microcontrollers, single 3.3V supply and low power consumption.

The TDA18211 silicon tuner from NXP, has been designed around the latest BiCMOS library, with NXP's highly-efficient system-in-package (SiP) technology for maximum reduction in manufacturers' bill-of-materials (BoM). Further BoM reduction is achieved with the integrated Loop Through output and Slave Tuner output that support PVR (Personal Video Recording) applications. The TDA18211HD silicon tuner for set-top boxes is now sampling and is expected to be in mass production by Q2 2007.
