1. General description
2. Features and benefits
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 and in-home video distribution capability.
Used in conjunction with the TDA10024HN (digital channel demodulator), the
TDA18254AHN covers all worldwide digital cable standards.
TDA18254AHN
Cable Silicon Tuner
Rev. 3 — 13 September 2010
Supports 4 tuner functions specifically aimed for PVR boxes:
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
Alignment free
