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
