Product details
Overview
SN75DP139RGZR from Texas Instruments is a DisplayPort-to-TMDS level-shifting re-driver IC designed for DP++ (Dual-Mode DisplayPort) interface translation in GPU-connected video routing systems. It supports up to 3.4 Gbps data rate, HDMI 1.4b compliance, 340 MHz TMDS clock, 4k×2k@30 Hz operation, and deep color up to 36 bpp - enabling direct integration into DP-to-HDMI/DVI dongles and docking stations.
For engineers reviewing the SN75DP139RGZR datasheet, SN75DP139RGZR pinout, SN75DP139RGZR application, or SN75DP139RGZR equivalent, this page delivers verified electrical specs, validated VQFN-48 pin mapping, real-world use cases in GPU video path extension, and two confirmed alternative re-drivers with documented functional and layout implications.
Technical Context
The SN75DP139RGZR implements a unidirectional DP physical layer input to TMDS physical layer output architecture with integrated receiver equalization and transmitter level-shifting. It processes four differential DP main link lanes (IN_D1–IN_D4) and converts them to four TMDS differential outputs (OUT_D1–OUT_D4), including clock lane remapping.
Its dual-mode operation is controlled via I2C_EN pin state (H/L) to select HDMI vs DVI timing profiles, while SRC and VSadj pins enable fine-grained control of TMDS edge rates and voltage swing compliance. The device includes active I2C buffering, HPD logic inversion (HPDINV), and integrated DDC enable (DDC_EN) for seamless EDID handshaking across sink-side interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DP-to-TMDS re-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN75DP159RGZR | Same RGZ package; supports higher 5.4 Gbps data rate and HDMI 2.0; adds spread-spectrum clocking | Required for 4k@60Hz, HDR, or HDMI 2.0 sink compatibility; consumes ~25% more power in active mode | Select SN75DP159RGZR when HDMI 2.0 or >3.4 Gbps bandwidth is required; not drop-in compatible due to different register map and timing constraints |
| PTN3360BSB | 40-pin WQFN (RSB) package; supports 3.4 Gbps but lacks integrated DDC buffer and HPD inversion logic | Requires external I2C buffer and HPD level-shifter; limited to DVI/HDMI 1.3a compliance; no 340 MHz clock support | Choose PTN3360BSB only for cost-sensitive DVI-only applications where integrated DDC/HPD features are unnecessary |
Compared with SN75DP139RGZR, SN75DP159RGZR enables next-generation HDMI bandwidth but increases layout complexity and power; PTN3360BSB reduces integration but requires additional components and sacrifices HDMI 1.4b features like 3D and deep color support.

FAQ
What is the primary function of the SN75DP139RGZR?
The SN75DP139RGZR is a DisplayPort-to-TMDS level-shifting re-driver IC that converts DP++ source signals into HDMI- or DVI-compliant TMDS outputs. It performs receiver equalization, level shifting, and timing adaptation - enabling direct connection of DP-enabled GPUs to HDMI/DVI displays without external protocol translation. Its design centers on physical-layer signal integrity, not packet-level video processing.
Does the SN75DP139RGZR support HDMI 2.0 or 4k@60Hz?
No, the SN75DP139RGZR supports up to 3.4 Gbps data rate and 340 MHz TMDS clock, which limits it to HDMI 1.4b - sufficient for 4k×2k@30 Hz, 1080p120, and 3D video, but not HDMI 2.0's 6 Gbps requirement for 4k@60Hz. For HDMI 2.0, TI recommends SN75DP159RGZR, which is pin-compatible in RGZ but requires updated firmware and layout validation.
How does the I2C_EN pin affect SN75DP139RGZR operation?
The I2C_EN pin configures the SN75DP139RGZR for HDMI (I2C_EN = High) or DVI (I2C_EN = Low) mode. In HDMI mode, it enables the internal I2C register for connector identification and selects the fastest TMDS edge rate. In DVI mode, the register is disabled and a slower edge rate is applied - ensuring compatibility with legacy DVI sinks that lack HDMI timing tolerance.
Can the SN75DP139RGZR be used without an external RVsadj resistor?
No - the RVsadj resistor (recommended 4.02 kΩ ±5%) is mandatory for setting TMDS output voltage swing to meet HDMI/DVI compliance. Omitting it results in non-compliant VOD(PP) (800–1200 mV) and failure in HDMI compliance testing. TI provides Figure 19 in the datasheet to guide selection based on system losses and AVCC variation.
Is the SN75DP139RGZR pin-compatible with the SN75DP139RSBR?
No - SN75DP139RGZR uses a 48-pin VQFN (7 mm × 7 mm), while SN75DP139RSBR uses a 40-pin WQFN (5 mm × 5 mm). Their pin counts, layouts, and signal assignments differ significantly (e.g., RGZ has dedicated HPD_SOURCE/HPD_SINK pins; RSB shares functions on fewer pins). Board redesign is required for substitution.
