CBTL12131ET,518

Video Processing Overview

The CBTL12131ET,518 is a DisplayPort high-speed path switch and multiplexer designed for all-in-one computer systems. It manages video routing between two GPU sources and integrated or external displays. The device supports DisplayPort v1.1a at 2.7 Gbit/s with four differential lanes per port for Main Link channels. It features configurable equalization, pre-emphasis, and swing levels for channel loss compensation. Powered by a single 3.3 V supply, it operates in dual-through or external source modes.

Video Processing Feature Summary

• Supports bidirectional video switching between internal and external DisplayPort connectors
• Configurable equalizer for channel loss compensation in external source mode
• Integrated HPD signal management with filtering to prevent false disconnect detection
• Board-strapping configuration for path selection and signal parameters without software

Video Processing Applications

• All-in-one computer systems requiring bidirectional DisplayPort connectivity
• Systems utilizing dual GPUs for simultaneous internal and external display output
• Applications involving external notebook computers connected as DisplayPort sources

Video Processing Procurement Notes

Verify the specific ordering suffix ET,518 against the manufacturer's current product data sheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required 3.3 V power supply and CMOS input logic levels. Confirm that board-strapping resistor values align with the specified quinary input configurations for equalization and pre-emphasis settings.

Video Processing Selection Notes

Select this component when designing all-in-one PCs needing flexible DisplayPort topology switching. It is suitable for applications requiring low insertion loss and support for both sink and source connections on the external connector. Consider its board-strapping configuration capabilities if software-based control over path selection and signal conditioning is not desired.

Video Processing Part Context

This part belongs to NXP's portfolio of high-speed interface switches. It complements other DisplayPort and USB signal conditioning devices by providing comprehensive path management for Main Link, AUX, and DDC channels. Its integration reduces the need for multiple discrete switches and complex control logic in bidirectional video designs.
