TDA18260HN/C1,551

Video Processing Overview

The TDA18260HN/C1,551 is a dual silicon tuner IC designed for high definition multi-tuner cable Set-Top Boxes. It supports single and multi-streaming PVR STBs with watch, record, video-on-demand, and in-home video distribution capabilities. The device operates within an RF frequency range of 42 MHz to 1002 MHz and utilizes a single 3.3 V power supply. Key electrical parameters include a maximum noise figure of 7.5 dB, phase noise of -85 dBc/Hz at 10 kHz offset, and image rejection of 62 dB typical. Power dissipation is typically 1.6 W.

Video Processing Feature Summary

• Dual tuner architecture integrated into a single small-sized package with one RF input and internal splitter
• Extended frequency coverage from 42 MHz up to 1002 MHz for multistandard cable reception
• Enhanced filtering scheme providing third and fifth harmonic suppression without external components
• Single crystal application capability supporting up to six streams including demodulators

Video Processing Applications

• High definition multi-tuner cable Set-Top Boxes (STBs)
• Multi-streaming Personal Video Recorder (PVR) STBs
• In-home video distribution systems

Video Processing Procurement Notes

Verify the specific ordering suffix /C1,551 against current NXP documentation to confirm package type and compliance status. Confirm that the product status aligns with design requirements, as availability may change. Ensure compatibility with the intended digital cable standards and demodulator interfaces before finalizing procurement.

Video Processing Selection Notes

Select this component for designs requiring dual tuner functionality within a compact footprint. It eliminates the need for external low noise amplifiers, SAW filters, and incremental crystal oscillators. Verify that the system can accommodate the single 3.3 V supply requirement and that the I2C-bus interface matches the controller's protocol.

Video Processing Part Context

This device is part of NXP Semiconductors' silicon tuner portfolio, specifically engineered for digital cable TV reception. It is often used in conjunction with the TDA10025HN dual digital channel demodulator to cover worldwide digital cable standards. The integration reduces system bill of materials by removing costly external passive components.
