TDA18260HN
Dual cable Silicon Tuner
Rev. 2 — 14 December 2010
Preliminary 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
2. Features and benefits
 Supports up to three tuner functions (up to six individual streams) specifically aimed
for gateways and STBs:
 Two low IF outputs
 Two RF outputs to drive slave tuners
 Integrated splitter eases and simplifies the design of dual Tuner PVR
 Integrated wideband gain control
 Extended frequency coverage up to 1002 MHz
 Single 3.3 V power supply
 Low power consumption
 Multistandard cable receptions
 Enhanced Band-pass filter to reduce in band third and fifth signal harmonics
 Enhanced RF filters to increase selectivity and adjacent channels filtering, especially
enhanced immunity for MoCA coexistence
