TDA18250HN
Cable Silicon Tuner
Rev. 2 — 14 January 2011
Preliminary data sheet
1. General description
The TDA18250HN is a Silicon Tuner IC designed specifically for high definition cable Set
Top Boxes (STB) supporting single streaming.
Used in conjunction with the TDA10024HN (digital channel demodulator), the
TDA18250HN covers all worldwide digital cable standards.
• The TDA18250HN 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 TDA18250HN high-performance Silicon Tuner meets today’s digital cable TV
reception needs with:
– Low power consumption
– High linearity
– Low noise figure
• The TDA18250HN ensures ease of use with:
– Easy on-board integration
– Efficient and effective PCB design
– Reduced external components
