The TDA18250A is a silicon tuner designed specifically for worldwide cable and terrestrial digital Set Top Boxes (STB).
* The TDA18250A 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 TDA18250A 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 TDA18250A ensures ease of use with:
* Easy on-board integration
* Efficient and effective PCB design
* Reduced external components
* Integrated Zero Power Loop-Through (ZPLT)
