SN75DP119RGYR

Overview

The SN75DP119RGYR is a DisplayPort signal repeater and conditioner manufactured by Texas Instruments. It supports DisplayPort versions 1.1a, 1.2, and 1.2a with data rates up to 8.1 Gbps per lane. The device operates on a single 3.3 V supply voltage and includes an integrated 1.2 V LDO regulator for internal logic power. It features a 48-pin VQFN package measuring 7x7 mm with a maximum height of 0.9 mm. The component functions as a 1:1 signal repeater, providing signal conditioning to extend cable lengths and maintain link integrity in display applications.

Feature Summary

• Provides 1:1 signal repetition and conditioning for DisplayPort links
• Supports high-speed data transmission up to 8.1 Gbps per lane
• Integrates a low-dropout regulator for simplified power management
• Compatible with DisplayPort 1.1a through 1.2a specifications

Applications

• Extending DisplayPort connections between source devices and displays
• Signal conditioning in docking stations and hubs
• Internal board-to-board interconnects requiring signal regeneration

Procurement Notes

Verify the specific suffix RGYR confirms the tape and reel packaging format required for automated assembly processes. Confirm that the 48-pin VQFN footprint matches the target PCB layout dimensions. Ensure the design accounts for the 3.3 V supply requirement and thermal dissipation characteristics associated with the active signal repeater function during operation.

Selection Notes

Select this component when signal degradation requires active regeneration rather than passive extension. The integrated LDO simplifies power rail design by eliminating the need for a separate 1.2 V supply. Consider the 7x7 mm package size for space-constrained designs. Verify compatibility with the specific DisplayPort version requirements of the host system to ensure proper data rate support.

Part Context

This part belongs to the SN75DP1xx series of DisplayPort interface controllers from Texas Instruments. It serves as a specialized solution for maintaining signal integrity in high-bandwidth video transmission paths. The device complements other interface components by handling the physical layer requirements for reliable digital video communication over extended distances or complex routing topologies.

Replacement Considerations

The SN75DP118 is a related repeater variant within the same family. Verify functional equivalence regarding supported data rates and pin compatibility before substitution. Cross-reference datasheet specifications to ensure the alternative meets the specific signal conditioning requirements of the application.
