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.
