TDA18252HN

DataSheet.in TDA18252HN Cable Silicon Tuner Rev. 3 — 16 August 2010 Product data sheet 1. General description The TDA18252HN is a single-chip direct conversion Silicon Tuner IC designed for digital-only cable applications. The TDA18252HN integrates a loop-through feature that enables the RF input signal to be used as an output for another downconverter. This feature simplifies the application and reduces the Bill Of Materials (BOM). The TDA18252HN ensures a low system cost as: – Costly components such as low-noise amplifiers, Surface Acoustic Wave (SAW) filters and incremental crystal oscillators are eliminated from the system BOM The TDA18252HN high-performance Silicon Tuner meets today’s digital cable TV reception needs with: – Low power consumption – High linearity – Low noise figure The TDA18252HN 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 power supply Low power consumption Extended frequency coverage of up to 1002 MHz Digital cable reception for STB RF loop-through Fully integrated IF selectivity; eliminating the need for external SAW filters Alignment free Fully integrated oscillator with no external components Integrated wideband gain control Crystal oscillator output buffer (16 MHz) for single crystal applications I2C-bus provides: ‹ 3.3 V and 5 V microcontroller compatibility ‹ Received Signal Strength Indicator (RSSI) ...
