TUA 6036 T

Video Processing Overview

The TUA6036 is a 3-band digital TV and set-top-box tuner IC from Infineon's TAIFUN family. It integrates a mixer-oscillator block with a digitally programmable phase-locked loop (PLL). The device supports PAL, NTSC, DVB-C, DVB-T, ISDB-T, and ATSC standards. It features wideband AGC detection, low phase noise, and full ESD protection. The PLL allows precise frequency setting up to 1024 MHz using a 4 MHz quartz crystal. It includes an IF amplifier capable of driving a compensated SAW filter and offers bus-controlled power-down modes.

Video Processing Feature Summary

• Integrates three balanced mixers for LOW, MID, and HIGH bands with dedicated oscillators
• Digitally programmable PLL with I2C interface supporting multiple reference divider ratios
• Wideband AGC detector with programmable take-over points and time constants
• Symmetrical IF preamplifier designed to drive compensated SAW filters directly

Video Processing Applications

• Digital terrestrial television tuners (DVB-T, ISDB-T, ATSC)
• Analog television tuners (PAL, NTSC)
• Set-top-box applications
• VCR tuners

Video Processing Procurement Notes

Verify the specific ordering code and package variant required for the design. The TUA6036 is available in PG-TSSOP-38 and PG-VQFN-48 packages. Confirm that the selected version matches the pin configuration and thermal requirements of the target application circuit. Ensure compatibility with the microcontroller's I2C voltage levels.

Video Processing Selection Notes

Select the TUA6036 when a single-chip solution for multi-standard TV tuning is required. It is suitable for designs needing integrated band switching and AGC control. Consider the VQFN package for compact layouts or the TSSOP package for standard surface mount assembly. Verify that the application supports the internal oscillator configurations and SAW filter interface requirements.

Video Processing Part Context

The TUA6036 belongs to the TAIFUN series of tuner ICs, developed by Infineon Technologies for consumer electronics. It is functionally related to the TUA6034, sharing similar core capabilities but differing in pinout or package options. This component addresses the need for integrated RF front-end solutions in digital and analog TV receivers, simplifying the design of tuner modules.

Video Processing Replacement Considerations

The TUA6034 is a closely related part within the same product family. Check the datasheet for pin compatibility and functional equivalence before substitution. Ensure that any replacement maintains support for the required broadcast standards and package type.
