SN75DP159RGZT

Overview

The SN75DP159RGZT is a dual-channel DisplayPort to HDMI retimer manufactured by Texas Instruments. It supports data rates up to 6 Gb/s and operates within an ambient temperature range of 0°C to +85°C. The device utilizes a 48-pin VQFN package with dimensions of 7.15 x 7.15 x 0.95 mm. Electrical specifications include a maximum power dissipation of 435 mW, an input capacitance of 10 pF, and a propagation delay of 360 ns. It functions on supply voltages of 1.1 V and 3.3 V, with operating limits between 1 V and 3.6 V.

Feature Summary

• Converts DisplayPort++ 1.1 signals to HDMI 2.0 format while maintaining signal integrity through retiming.
• Integrates two independent channels for simultaneous high-speed video transmission processing.
• Supports I2C interface communication for configuration and status monitoring during operation.

Applications

• High-definition display interfaces requiring signal regeneration
• Video processing systems converting DP sources to HDMI sinks
• Consumer electronics utilizing DisplayPort inputs

Procurement Notes

Verify the specific suffix 'RGZT' confirms the VQFN-48 package and tape-and-reel delivery method. Confirm the '75' prefix indicates the commercial temperature grade (0°C to +85°C) rather than the industrial '-65°C to +125°C' grade found in SN65 variants. Ensure compatibility with required I2C clock frequencies not exceeding 400 kHz.

Selection Notes

Select this component when a commercial-grade retimer is sufficient for the application environment. The VQFN-48 package offers a compact footprint suitable for space-constrained designs. Verify that the system power budget accommodates the specified 435 mW dissipation. Consider the SN65DP159RGZT if extended temperature ranges are required.

Part Context

This part belongs to the SN75DP159 series of DisplayPort to HDMI retimers. It serves as a signal conditioning solution for high-bandwidth digital content protection applications. The device complements other interface ICs by bridging protocol differences between source and sink devices in modern multimedia systems.
