Overview

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.
Features and benefits  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 and 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 NXP Semiconductors TDA18250BHN Cable silicon tuner  LT output  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 HBM) on RF_IN and LT pins  Alignment free  Excellent return loss compatible with cable requirements  Integrated RSSI function, readable through I2C-bus  Integrated temperature sensor  Integrated gain control 3.
