TDA18250HN Cable Silicon Tuner Rev. 6 22 December 2011 Product short data sheet 1. General description The TDA18250 is a silicon tuner IC designed specifically for high definition cable Set-Top Boxes (STB) supporting single streaming. Used in conjunction with a digital channel demodulator, the TDA18250 covers all worldwide digital cable standards. The TDA18250 ensures a low system cost as: Costly components such as low-noise amplifiers, Surface Acoustic Wave (SAW) filters are eliminated from the system BOM The TDA18250 high-performance silicon tuner meets todays digital cable TV reception needs with: Low power consumption High linearity Low noise figure The TDA18250 ensures ease of use with: Easy on-board integration Efficient and effective PCB design Reduced external components 2. Features and benefits RF frequency coverage up to 1002 MHz Integrated wideband gain control LOW IF (LIF) output Single 3.3 V power supply Low power consumption Multistandard cable receptions Fully integrated IF selectivity, eliminating the need for external SAW filters RF Loop-Through (LT) Enhanced RF and IF filters to increase selectivity and adjacent channels filtering Alignment free Fully integrated oscillators: No external oscillator components for reduced cost 16 MHz crystal oscillator output buffer for single crystal applications Supports 2 tuner functions specifically aimed for PVR boxes: 1 RF output to drive slave tunerTDA18250HN NXP Semiconductors Cable Silicon Tuner 2 I C-bus provides: 3.3 V microcontroller compatibility Received Signal Strength Indicator (RSSI) data access Die temperature sensor data access Lead-free (Pb) manufacturing 3.
