Cable Silicon Tuner
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)
