TUA 6020

Video Processing Overview

The TUA6020 is a 5 V mixer/oscillator and synthesizer for analog and digital TV and VCR tuners. It integrates a digitally programmable phase locked loop (PLL) with a mixer-oscillator block containing two balanced mixers and oscillators. The PLL permits precise frequency setting up to 1024 MHz using a 4 MHz quartz crystal, with increments of 31.25, 50, 62.5 or 166.7 kHz. Supply voltage ranges from +4.5 V to +5.5 V. The device operates within an ambient temperature range of -20 °C to +85 °C.

Video Processing Feature Summary

• Integrates a digitally programmable phase locked loop with short lock-in time and high voltage VCO tuning output
• Features two balanced mixers with distinct high impedance input for LOW/MID band and low impedance input for HIGH band
• Includes two frequency and amplitude-stable balanced oscillators for LOW/MID and HIGH bands
• Provides full ESD protection and a balanced SAW preamplifier with low output impedance

Video Processing Applications

• Analog terrestrial TV tuner sets
• Digital Video Broadcasting set-top receivers
• VCR tuner modules

Video Processing Procurement Notes

Verify the specific ordering code Q67037-A1127-A701 against current Infineon documentation to confirm availability and package configuration. Ensure design compliance with absolute maximum ratings, particularly regarding supply voltage limits and thermal resistance constraints during integration.

Video Processing Selection Notes

Select this component for applications requiring integrated PLL control via I2C bus and dual-band mixer functionality. Consider the P-TSSOP-28-1 package dimensions and pinout requirements. Evaluate the programmable reference divider ratios and charge pump current settings to match specific VCO gain characteristics in the target tuner design.
