TDA18250BHN

TDA18250BHN Cable silicon tuner Rev. 2 — 10 July 2013 Product short data sheet 1. General description The TDA18250B is a silicon tuner designed specifically for worldwide cable and terrestrial digital Set Top Boxes (STB). The TDA18250B ensures a low system cost by saving external components such as: – Low-Noise Amplifiers – Surface Acoustic Wave (SAW) filters – RF splitter Moreover, thanks to its 8 kV ESD capability, EIA/JESD22-A114 (HBM), on the RF input pin and the loop-through pin, the application level ESD protection can be reduced. The TDA18250B silicon tuner meets current and future digital cable and terrestrial TV reception with: – Low-power consumption – High linearity – Very low noise figure (3.8 dB typical) – High immunity to wireless interferers (WLAN, LTE and GSM) The TDA18250B ensures ease of use with: – Easy on-board integration – Efficient and effective PCB design – Reduced external components 2.
