KTS 6027-2

Video Processing Overview

The KTS6027-2 is a 5 V mixer, oscillator, and synthesizer IC designed for analog and digital TV/VCR tuners. It integrates a digitally programmable PLL with a mixer-oscillator block containing two balanced mixers and oscillators for LOW/MID and HIGH bands. The device supports frequency setting up to 1024 MHz using a 4 MHz quartz crystal, with increments of 31.25, 50, 62.5, or 166.7 kHz. It features an unbalanced IF amplifier with 75 Ω output impedance, four NPN bandswitch buffers, and full ESD protection.

Video Processing Feature Summary

• Integrates a digitally programmable phase locked loop (PLL) with short lock-in time and high voltage VCO tuning output.
• Includes a mixer-oscillator block with dual balanced mixers and oscillators for distinct LOW/MID and HIGH frequency bands.
• Features a single-ended IF preamplifier with 75 Ω output impedance and internal band switching logic.
• Provides fast I2C bus interface control with programmable reference divider ratios and charge pump currents.

Video Processing Applications

• Analog terrestrial TV tuners
• Digital (ATSC) TV tuners
• VCR tuner circuits
• CATV set-top receivers

Video Processing Procurement Notes

Verify the specific ordering code Q67037-A1162 for tape and reel packaging when sourcing. Confirm compatibility with existing system designs by checking pin configuration against the KTS6029-2 variant, which utilizes reversed pinning. Ensure supply voltage remains within the specified 4.5 V to 5.5 V operating range during integration.

Video Processing Selection Notes

Select this component for applications requiring integrated PLL synthesis and mixing in a single package. Consider the P-TSSOP-28-1 package for surface mount assembly. Evaluate the need for extended mode features, such as the 24 reference divider ratio, if faster lock times are required compared to standard operation compatible with previous KTS6027-S models.

Video Processing Part Context

This device belongs to Infineon's wireless components portfolio, specifically targeting consumer electronics like television and video recording equipment. It serves as a direct successor or alternative to earlier models like the KTS6027-S, offering enhanced programmability through the I2C bus while maintaining backward compatibility in normal mode operations.

Video Processing Replacement Considerations

The KTS6029-2 is a compatible variant within the same family but features reversed pinning compared to the KTS6027-2. Designers must verify pinout alignment before substitution. No other direct cross-model replacements are documented in the provided specification.
