SN75DP119RGYT

Overview

The SN75DP119RGYT is a DisplayPort 1:1 signal repeater and conditioner manufactured by Texas Instruments. It operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum operating current of 110 mA. The device supports data rates up to 2.7 Gbps per lane and functions at a maximum frequency of 250 MHz. It is housed in a WQFN-40 package and is rated for an ambient operating temperature range from 0°C to +85°C. The component includes integrated equalization and clock recovery circuits to maintain signal integrity over extended cable lengths.

Feature Summary

• Provides active signal regeneration and conditioning for DisplayPort links
• Integrates continuous-time linear equalization (CTLE) to compensate for channel loss
• Supports hot-plug detection and link training protocols
• Includes built-in clock recovery circuitry for jitter attenuation

Applications

• Extending DisplayPort connections beyond standard cable length limits
• Signal conditioning in high-resolution display docking stations
• Active cables and extender systems for professional AV equipment

Procurement Notes

Verify the specific suffix RGYT against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the ordering information matches the exact package type and moisture sensitivity level required for your assembly process. Cross-reference the part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when extending DisplayPort signals requires active equalization rather than passive cabling. Compare performance metrics such as insertion loss tolerance and jitter reduction capabilities against alternative repeaters. Consider the power consumption and thermal dissipation requirements of the WQFN-40 package in relation to the host system's design constraints.

Part Context

This part belongs to the SN75DP1xx series of DisplayPort interface ICs from Texas Instruments. It serves as a signal conditioner designed to bridge the gap between source devices and displays where signal degradation occurs. The series typically includes variants for different package sizes and thermal performances, all sharing core repeater functionality.

Replacement Considerations

Direct substitutes may include other SN75DP119 variants with different suffixes indicating package or tape/reel options. Verify electrical equivalence before substitution. No other cross-manufacturer replacements are publicly confirmed without additional engineering validation.
