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
■ Dual tuner inside one single, small sized package
   ♦ One single RF input with direct cable connection
   ♦ Internal splitter to drive the two integrated tuners
   ♦ Two low IF outputs, connecting directly to demodulators
■ RF loop-through
■ Easy application for up to 6-tuner using 3 TDA18260HN
   ♦ Dedicated multiple tuner outputs to drive additional tuners
   ♦ No need for external active splitter
   ♦ Same performance on all streams
■ Extended frequency coverage from 42 MHz up to 1002 MHz
■ Multistandard cable receptions
■ Enhanced filtering scheme with no external components
   ♦ Third and fifth signal harmonics suppression
   ♦ Optimum adjacent channel rejection
   ♦ MoCA rejection reduces the complexity and the cost of the triplexer
■ Single 3.3 V power supply with low power consumption
■ Single crystal application for up to 6 streams, including demodulators
■ High accuracy Received Signal Strength Indicator (RSSI)
■ Dual I2C-bus provides full flexibility in programming the two streams from one SoC or
   independently from two SoCs
