Product Description

Overview
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)

## Features
* Single 3.3 V supply voltage
* RF frequency coverage up to 1 GHz
* Flexible low IF output from 3 MHz to 7.5 MHz to ease the matching with various demodulators
* RoHS compliant
* I²C-bus interface compatible with 3.3 V microcontrollers
* Strong Immunity to wireless interferers (WLAN, GSM, LTE)
* Multi-reference clock frequency compliant: 16 MHz, 24 MHz, 25 MHz, 27 MHz, 30 MHz
* Crystal oscillator output buffer to drive demodulator, SoC or slave tuner
* Slave Tuner Output (STO), integrated splitter for dual tuner applications
* Fully integrated oscillators
* LT output, both in active and Zero Power Loop-Through mode (ZPLT)
* Fully integrated IF and RF selectivity; eliminating the need for external SAW filters
* Single-ended RF input (no need for external balun)
* Enhanced ESD protection (8 kV) on RF_IN and ZPLT pins
* Alignment free
* Excellent return loss compatible with cable requirements
* Integrated RSSI function, readable through I²C-bus
* Integrated temperature sensor
* Integrated gain control
## Target Applications
