TDA18219HN/C1,551

Video Processing Overview

The TDA18219HN is a silicon tuner for terrestrial and cable digital TV reception. It supports DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C standards. The device delivers a LOW IF signal to a channel demodulator. It operates within an RF frequency range of 42 MHz to 870 MHz. The typical tuner noise figure is 5.0 dB with a maximum of 5.9 dB at a 75 Ω source. The image rejection is typically 63 dB. The 1 dB input compression point is -124 dBμV. Phase jitter in the UHF band is typically 0.5 degrees. The device requires a single 3.3 V supply voltage.

Video Processing Feature Summary

• Fully integrated IF selectivity eliminates the need for external SAW filters
• Integrated oscillators provide alignment-free operation

Video Processing Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package configuration. Confirm RoHS compliance status as required by regional regulations. Check the latest product data sheet for any updates regarding limiting values or recommended operating conditions before finalizing design integration.

Video Processing Selection Notes

Select this component for designs requiring a fully integrated tuner solution without external SAW filters. Ensure the system architecture accommodates a single 3.3 V supply. Verify that the host microcontroller supports the I2C-bus interface at the specified voltage levels. Consider the physical dimensions of the HVQFN40 package during PCB layout planning.

Video Processing Part Context

This part belongs to NXP's silicon tuner portfolio designed for digital TV applications. It integrates RF front-end functions including LNA, mixer, and oscillators into a single chip. The device simplifies board design by removing the requirement for discrete filtering components typically needed in traditional tuner architectures.

Video Processing Replacement Considerations

Consult official NXP documentation for verified substitute part numbers. Cross-reference specifications such as RF frequency range, noise figure, and package type when evaluating alternatives.
