TDA18218HN/C1,551

Video Processing Overview

The TDA18218HN is a silicon tuner IC designed for digital terrestrial (DVB-T) TV reception. It integrates the complete tuning function, including selectivity and low-IF output signal generation. The device supports 6 MHz, 7 MHz, or 8 MHz channel bandwidths using integrated IF filters. It requires only a single 16 MHz crystal for clock generation and provides a synchronized clock output for the channel decoder. Operating on a single 3.3 V supply, it delivers low power consumption of approximately 750 mW in normal mode.

Video Processing Feature Summary

• Fully integrated IF selectivity eliminates the need for external SAW filters
• Integrated oscillators require no external components
• Includes RF loop-through capability for Set-Top Box implementation
• Features an integrated die thermal sensor

Video Processing Applications

• DVB-T Set-Top Box (STB)
• Digital TV receiver

Video Processing Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. Ensure the I2C address configuration via pin AS matches the system design requirements. Confirm that the HVQFN48 package dimensions align with the PCB layout constraints. Check compatibility with the intended channel decoder for proper AGC and IF level settings.

Video Processing Selection Notes

Select this component for applications requiring a cost-effective silicon tuner solution for DVB-T standards. Consider the integrated features when designing systems where space and power consumption are critical constraints. Evaluate the need for RF loop-through functionality if the design requires passing RF signals to other stages without additional amplification.
