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
  
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
■ RF Loop-Through (LT)
■ Fully integrated IF selectivity, eliminates external SAW filters
