TDA18254AHN  
Cable Silicon Tuner  
Rev. 4 — 10 May 2011  
Product short data sheet  
1. General description  
The TDA18254AHN is a Silicon Tuner IC designed specifically for high definition  
multi-tuner cable Set Top Boxes (STB) supporting single streaming and multi-streaming  
PVR STBs with watch, record, Video-On-Demand (VOD) and in-home video distribution  
capability.  
Used in conjunction with the TDA10024HN (digital channel demodulator), the  
TDA18254AHN covers all worldwide digital cable standards.  
The TDA18254AHN 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 TDA18254AHN high-performance Silicon Tuner meets today’s digital cable TV  
reception needs with:  
Same level of performance for master and slave tuners  
Low power consumption  
High linearity  
Low noise figure  
The TDA18254AHN ensures ease of use with:  
Easy on-board integration  
Efficient and effective PCB design  
Reduced external components  
2. Features and benefits  
„ Supports 4 tuner functions specifically aimed for PVR boxes:  
‹ 1 × low IF output  
‹ 3 × RF outputs to drive slave tuners  
„ Integrated wideband gain control  
„ Extended frequency coverage up to 1002 MHz  
„ Integrated RF tracking filters for rejection of unwanted signals  
„ Single 3.3 V power supply  
„ Low power consumption  
„ Multistandard cable receptions  
„ Enhanced RF and IF filters to increase selectivity and adjacent channels filtering  
„ RF loop-through  
„ Fully integrated IF selectivity, eliminating the need for external SAW filters
