SN75DP139RGZR

Specialized Overview

The SN75DP139RGZR is a DisplayPort to TMDS translator manufactured by Texas Instruments. It converts DisplayPort signals to TMDS format for HDMI or DVI displays. The device operates within a supply voltage range of 3 V to 3.6 V and supports a maximum operating frequency of 250 MHz. It draws an operating current of 110 mA. The component is housed in a 48-pin VQFN package with dimensions of 7.15 x 7.15 x 0.95 mm. It functions reliably across a temperature range of 0°C to +85°C.

Specialized Feature Summary

• Performs translation from DisplayPort input signals to TMDS output signals compatible with HDMI or DVI interfaces.
• Integrates level-shifting and re-driving capabilities to maintain signal integrity over cable runs.
• Supports high-speed data transmission up to 250 MHz for digital video applications.

Specialized Applications

• Desktop computer display connections
• Laptop external monitor interfaces
• HDMI and DVI display adapters

Specialized Procurement Notes

Verify the specific suffix 'RGZR' against the manufacturer's latest datasheet to confirm the tape-and-reel packaging configuration. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design, as minor suffix variations may indicate different packaging or testing criteria.

Specialized Selection Notes

Select this component when a direct interface between a DisplayPort source and a TMDS-based sink is required without external logic. Confirm that the system power supply remains stable between 3 V and 3.6 V. Verify that the thermal dissipation requirements fit within the VQFN-48 package constraints for the intended ambient temperature conditions.

Specialized Part Context

This part belongs to the SN75DP139 series of display interface ICs from Texas Instruments. It serves as a bridge between modern DisplayPort sources and legacy or standard TMDS displays. The RGZR variant specifically denotes the reel-packaged version of the active component, distinct from cut-tape or tray options.

Specialized Replacement Considerations

The SN75DP139RGZT is a functional equivalent within the same family, differing primarily in packaging type rather than core electrical performance. Other series members like the SN75DP129 offer similar translation but may lack integrated re-driving features.
