TDA18260HN
Dual cable silicon tuner
Rev. 5 — 4 July 2012
Product short data sheet
1. General description
The TDA18260HN is a dual silicon tuner IC designed specifically for high definition
multi-tuner cable Set-Top Boxes (STBs) 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 TDA10025HN (dual digital channel demodulator), the
TDA18260HN covers all worldwide digital cable standards.
• The TDA18260HN ensures a low system cost as:
– Costly components such as low noise amplifiers, Surface Acoustic Wave (SAW)
filters and incremental crystal oscillators have been eliminated from the system Bill
Of Materials (BOM)
• The TDA18260HN high performance silicon tuner meets today’s digital cable TV
reception needs with:
– Matched performance levels for master and slave tuners
– Low power consumption
– High linearity
– Low noise figure
• The TDA18260HN ensures ease of use with:
– Easy on-board integration
– Efficient and effective PCB design
– Reduced external components
