GS12142-INTE3

Video Processing Overview

The GS12142-INTE3 is a low-power, multi-rate reclocking adaptive cable equalizer and trace equalizer supporting data rates up to 12G UHD-SDI. It features two independent channels with integrated 75Ω cable input interfaces and 100Ω trace input terminals. The device includes an embedded clock recovery (CDR) circuit for retiming incoming data across various standards from 1Mb/s to 11.88Gb/s. It operates on a single 1.8V supply voltage within a -40°C to +85°C temperature range.

Video Processing Feature Summary

• Dual-channel architecture combining adaptive cable equalization and trace equalization capabilities
• Integrated clock data recovery (CDR) for signal retiming across multiple video standards
• Built-in 3D eye monitor for non-intrusive signal analysis and troubleshooting
• Configurable trace drivers with pre-emphasis and swing control for PCB loss compensation

Video Processing Applications

• 12G UHD-SDI broadcast infrastructure equipment
• Signal distribution systems requiring long coaxial cable reach
• Professional video processing units needing jitter management
• Multiviewers and switchers in live production environments

Video Processing Procurement Notes

Verify the specific suffix 'INTE3' against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as required by your assembly specifications. Check for any recent Product Change Notifications (PCN) that may affect pinout or electrical characteristics before finalizing design integration.

Video Processing Selection Notes

Select this component when dual-channel retiming with both cable and trace equalization is required in a single footprint. It serves as a functional upgrade over the GS12141 by adding a second channel while maintaining pin compatibility with other devices in the GS121xx family. Ensure system power budget accommodates the dual-channel operation at maximum data rates.

Video Processing Part Context

This part belongs to Semtech's GS121xx series of high-performance video interface solutions designed for professional broadcast applications. It complements single-channel variants like the GS12141 and driver-only counterparts such as the GS12182. The series focuses on extending transmission distances and maintaining signal integrity in complex 12G UHD-SDI routing architectures.

Video Processing Replacement Considerations

The GS12141-INTE3 is a single-channel variant within the same family and offers pin compatibility. For dual-channel requirements without trace equalization, the GS12241-INTE3 may be considered if the application does not require onboard trace buffering.
