Product details
Overview
SN75DP159RSBT from Texas Instruments is a 6-Gbps AC-coupled TMDS™ to HDMI™ level shifter retimer IC supporting HDMI 2.0b electrical compliance, adaptive/fixed receiver equalization up to 16.5 dB, and automatic redriver/retimer mode selection based on data rate. It operates across 0°C to 85°C and delivers 435 mW active power at 6 Gbps in retimer mode for HDMI dongle and docking station signal integrity restoration.
For engineers reviewing the SN75DP159RSBT datasheet, SN75DP159RSBT pinout, SN75DP159RSBT application, or SN75DP159RSBT equivalent, this page provides verified package mapping (40-pin WQFN, 5 mm × 5 mm), confirmed lane-level TMDS retiming functionality, I²C/pin-strap configuration support, HDMI 2.0b output compliance, and thermal performance data for industrial embedded video interface designs.
Technical Context
The SN75DP159RSBT implements dual-mode DisplayPort-to-HDMI conversion with integrated clock data recovery (CDR) and adaptive equalization to suppress inter-symbol interference from lossy cables or PCB traces. Its receiver supports both AC-coupled TMDS and DisplayPort dual-mode physical layer inputs, while the transmitter provides programmable pre-emphasis, slew rate control, and TMDS output amplitude adjustment via Vsadj resistor.
It features automatic mode switching: redriver operation below 1 Gbps and retimer operation above that threshold-configurable via I²C or pin strapping. The device includes fail-safe HPD, DDC/I²C-over-AUX bridging, and independent source/sink-side DDC channel buffering for robust HDMI handshake and EDID communication in dongle and adapter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 6 Gbps per lane - enables Ultra HD 4K×2K/60 Hz (8-bit color) and 1080p/60 Hz with 16-bit color depth. |
| Operating Temperature | 0°C to 85°C - extended commercial grade suitable for consumer and industrial docking stations and adapters. |
| Power Dissipation | 435 mW typical at 6 Gbps retimer mode - enables thermally constrained WQFN packaging without forced cooling. |
| Equalization | Adaptive + fixed up to 16.5 dB - compensates for >15 dB channel loss from long cables or high-loss FR4 traces. |
| Input Compatibility | AC-coupled TMDS or DP++ dual-mode input - supports legacy HDMI sources and modern DisplayPort graphics outputs. |
| Output Compliance | HDMI 2.0b TMDS electrical parameters - ensures interoperability with certified HDMI 2.0b sinks without signal rework. |
| Package | 40-pin WQFN (5 mm × 5 mm, 0.4 mm pitch) - space-efficient footprint for compact dongles and PCB edge-mount designs. |
Pinout & Package
SN75DP159RSBT uses a 40-pin WQFN package (5.00 mm × 5.00 mm, 0.4 mm pitch) with exposed thermal pad connected to ground. Pin functions are validated per TI SLLSEJ2G datasheet Rev. March 2020, Section 6 (Pin Configuration and Functions) and Table "RSB Package".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_D0p / IN_D0n IN_D1p / IN_D1n IN_D2p / IN_D2n IN_CLKp / IN_CLKn |
Differential TMDS/DP++ input lanes | Accept AC-coupled DisplayPort dual-mode or TMDS signals; support lane swap and polarity inversion via SWAP/POL pin. |
| OUT_D0p / OUT_D0n OUT_D1p / OUT_D1n OUT_D2p / OUT_D2n OUT_CLKp / OUT_CLKn |
Differential HDMI TMDS output lanes | Drive HDMI-compliant TMDS signals with programmable swing (via Vsadj), slew rate (SLEW_CTL), and de-emphasis (PRE_SEL). |
| HPD_SRC / HPD_SNK | Hot-plug detect interface | HPD_SRC drives sink-side HPD line; HPD_SNK monitors source-side HPD with failsafe logic for plug/unplug detection. |
| SDA_SNK / SCL_SNK SDA_SRC / SCL_SRC |
Bi-directional DDC channels | Isolate and buffer source/sink DDC lines to prevent EDID corruption during hot-plug events in dongle topologies. |
| OE | Operation enable/reset | Pull low to enter 10 mW shutdown mode; internal weak pullup enables hardware reset on rising edge transition. |

Configuration control pins | Enable pin-strapped setup (I2C_EN/PIN = L) for fixed-function deployment without firmware overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CDR + adaptive equalizer | Removes high-frequency jitter and ISI from degraded DP/HDMI source signals, enabling reliable 4K/60 link budget extension. |
| Fail-safe HPD and DDC isolation | Prevents EDID read failures and display enumeration issues when connecting unpowered or non-compliant HDMI sources. |
| Programmable TMDS output swing | Vsadj pin accepts 4.5–7.5 kΩ resistor to set compliant HDMI output amplitude - eliminates need for external DAC or trimming. |
| Automatic redriver/retimer mode | Switches between redriver (<1 Gbps) and retimer (>1 Gbps) modes without software intervention - simplifies system initialization. |
| I²C-over-AUX bridge support | Enables GPU-side I²C access to HDMI sink EDID and DPCD registers through DisplayPort AUX channel - critical for Type-2 dongles. |
Applications
| HDMI Dongle | Docking Station |
|---|---|
|
Use Scenario: Converting DisplayPort output from laptop GPU to HDMI input on monitor or projector via compact USB-C or MiniDP dongle. IC Role / Device Role / Timing Role: Retimer restoring signal integrity across lossy passive cable and board trace; performs HDMI 2.0b TMDS level shifting and CDR.

| Gaming Console Adapter | Industrial Display Interface |
|
Use Scenario: Adapting next-gen gaming console DP++ output to legacy HDMI displays with strict jitter tolerance requirements. IC Role / Device Role / Timing Role: Adaptive equalizer cleans channel-induced jitter; CDR removes random jitter from GPU PHY before HDMI output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar TMDS retiming applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65DP159RSBT | Industrial temperature range (–40°C to 85°C); same 40-pin WQFN package and pinout. | Required for automotive or outdoor-rated docking systems operating beyond 0°C ambient. | Select when extended temperature operation is mandatory; otherwise SN75DP159RSBT offers identical functionality at lower cost. |
| TI TPD158RSBT | No CDR; redriver-only; no adaptive equalization; lower power (215 mW at 6 Gbps). | Suitable only for short-reach (<1 m) HDMI links with minimal channel loss; cannot recover jitter or extend 4K/60 reach. | Choose only for cost-sensitive, low-jitter source environments where retiming is unnecessary - not a functional replacement. |
Compared with SN65DP159RSBT, SN75DP159RSBT trades industrial temperature range for extended commercial qualification - ideal for consumer docks and dongles. Compared with TPD158RSBT, SN75DP159RSBT adds CDR and adaptive EQ, enabling robust 4K/60 transmission over lossy channels where TPD158RSBT would fail compliance testing.

FAQ
What is the maximum data rate supported by SN75DP159RSBT?
SN75DP159RSBT supports up to 6 Gbps per TMDS lane, enabling full HDMI 2.0b compliance for Ultra HD 4K×2K/60 Hz (8-bit color) and 1080p/60 Hz with 16-bit color depth. This rate is validated under recommended operating conditions with 1200 mV peak-to-peak differential input voltage and proper AC coupling capacitance (75–200 nF).
Does SN75DP159RSBT require external configuration firmware?
No - SN75DP159RSBT supports full pin-strapped configuration via I2C_EN/PIN = Low, allowing fixed-function deployment without microcontroller firmware. Key settings like equalization mode (EQ_SEL/A0), de-emphasis (PRE_SEL), slew rate (SLEW_CTL), and HDMI/DVI selection (HDMI_SEL/A1) are all controllable through resistor pulls or open-circuit states.
How does SN75DP159RSBT handle hot-plug detection in dongle applications?
SN75DP159RSBT implements fail-safe HPD logic: HPD_SRC actively drives the sink-side HPD line, while HPD_SNK monitors the source-side HPD with built-in protection against floating or noisy signals. This dual-path architecture prevents false plug/unplug detection and ensures reliable EDID handshaking in compact dongle form factors.
Can SN75DP159RSBT be used with DisplayPort sources that do not support dual-mode?
Yes - SN75DP159RSBT accepts standard AC-coupled TMDS inputs in addition to DP++ dual-mode signaling. When connected to non-dual-mode DisplayPort sources, it operates as a pure TMDS retimer, leveraging its CDR and equalization to restore signal integrity without requiring AUX channel negotiation or DPCD reads.
What thermal design guidance applies to SN75DP159RSBT in a 5 mm × 5 mm WQFN package?
SN75DP159RSBT has a junction-to-board thermal resistance (RθJB) of 9.9°C/W for the RSB (WQFN) package. To maintain case temperature ≤93.5°C at 435 mW dissipation, use ≥200 mm² copper pour connected to the exposed thermal pad, minimum 4 thermal vias (0.3 mm diameter), and avoid enclosing the IC in sealed enclosures without airflow.
