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 leader and follower 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
