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
