SN75DP139RGZT

Specialized Overview

The SN75DP139RGZT is a DisplayPort to TMDS translator manufactured by Texas Instruments. It converts DisplayPort signals to HDMI-compatible TMDS outputs. 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 x 7 mm. It functions reliably across an ambient temperature range from 0°C to +85°C.

Specialized Feature Summary

• Translates DisplayPort source signals into TMDS format for downstream display interfaces
• Integrates a high-speed serializer to manage differential data transmission
• Supports standard video timing formats compatible with HDMI sinks

Specialized Applications

• Desktop computer graphics cards
• Laptop motherboard display outputs
• All-in-one PC internal video bridges

Specialized Procurement Notes

Verify the specific suffix RGZT corresponds to the VQFN-48 package and tape-and-reel shipping configuration. Confirm RoHS compliance status matches current regulatory requirements. Ensure the ordering part number aligns with the intended reel quantity and moisture sensitivity level specifications provided in the official datasheet.

Specialized Selection Notes

Select this component when a system requires conversion from a DisplayPort source to a TMDS-based sink interface. Verify that the host controller provides compatible DisplayPort lane configurations. Ensure the PCB layout accommodates the 48-pin VQFN footprint and thermal requirements for continuous operation at elevated temperatures.

Specialized Part Context

This part belongs to the SN75DP139 series of display interface integrated circuits. It serves as a bridge between modern digital display sources and legacy or alternative display panel interfaces. The series is designed for integration into compact electronic devices requiring reliable video signal translation without external protocol converters.

Specialized Replacement Considerations

The SN75DP139RGZR is a verified substitute offering identical functionality in a tray package instead of cut tape. Other variants in the SN75DP139 family may differ in pin count or package type, requiring schematic and layout verification before substitution.
