Dual-Cable Silicon Tuner
TDA18260HN アラートの受信
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
