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
