TDA18275AHN/C1518

Video Processing Overview

The TDA18275 is a high-performance silicon tuner designed for terrestrial and cable TV reception supporting both analog and digital broadcasts. It delivers a Low IF signal to demodulators with an RF frequency range of 42 MHz to 1002 MHz. The device operates on a single 3.3 V supply voltage and features integrated oscillators, RF selectivity, and IF filters. Key electrical parameters include a typical noise figure of 3.3 dB below 870 MHz and 4.5 dB above 870 MHz, phase jitter of 0.6 degrees, and image rejection of -65 dB.

Video Processing Feature Summary

• Supports worldwide multistandard terrestrial and cable capabilities for analog and digital TV
• Fully integrated oscillators and RF selectivity eliminating the need for external tracking filter coils
• Strong immunity to LTE interferers in the digital dividend bandwidth and WLAN interferers
• Includes dual IF output ports and two programmable General-Purpose Outputs

Video Processing Applications

• Terrestrial TV reception
• Cable TV reception
• Analog broadcast systems
• Digital broadcast systems

Video Processing Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with 3.3 V microcontroller I2C interfaces. Confirm RoHS compliance status for your region. Validate that the application design respects the absolute maximum ratings for supply voltage and junction temperature to prevent permanent damage.

Video Processing Selection Notes

Select this component for designs requiring a hybrid silicon tuner with low BOM due to integrated RF and IF filtering. It is suitable for applications needing strong interference immunity against LTE and WLAN signals. Consider the HVQFN32 package dimensions (5 x 5 mm) for PCB layout constraints. Verify support for required channel bandwidths including 1.7, 6, 7, 8, and 10 MHz.

Video Processing Part Context

The TDA18275 belongs to NXP's family of silicon tuners for TV reception. It facilitates TV design by allowing on-board integration and drastically reducing the Bill Of Material. The device provides flexibility in system solution development by offering fully integrated components that eliminate the need for external SAW filters and baluns.

Video Processing Replacement Considerations

Consult NXP documentation for direct replacements or pin-compatible alternatives within the TDA182xx series. Verify functional equivalence regarding supported standards and interface compatibility before substitution.
