TDA18250AHN Cable silicon tuner Rev. 1 10 July 2013 Product short data sheet 1. General description 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) 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 2 I C-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 applicationsTDA18250AHN NXP Semiconductors Cable silicon tuner 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 HBM) on RF IN and ZPLT pins Alignment free Excellent return loss compatible with cable requirements 2 Integrated RSSI function, readable through I C-bus Integrated temperature sensor Integrated gain control 3.
