Product details
Overview
SN65DP149RSBR from Texas Instruments is a dual-mode DisplayPort++ to HDMI/DVI retimer IC supporting up to 3.4 Gbps per lane, integrated CDR and adaptive/fixed equalization, with 40-pin WQFN (5 mm × 5 mm) packaging, designed for GPU-to-monitor signal integrity restoration in 4K/30-Hz and 1080p/60-Hz video dongles and docking stations.
For engineers reviewing the SN65DP149RSBR datasheet, SN65DP149RSBR pinout, SN65DP149RSBR application, or SN65DP149RSBR equivalent, this page delivers verified electrical specs, validated TMDS output compliance, confirmed industrial temperature range (–40°C to 85°C), real-world retimer/redriver mode behavior, and precise I²C/pin-strap configuration logic - all directly traceable to TI's SLLSEL2C production data sheet.
Technical Context
The SN65DP149RSBR implements a full retimer architecture above 1.0 Gbps (with embedded CDR cleaning high-frequency jitter) and auto-switches to redriver mode below 1.0 Gbps. Its receiver includes both adaptive and fixed equalization (7.5 dB or 14 dB selectable via EQ_SEL/A0), while transmitter supports programmable de-emphasis (–2 dB or 0 dB via PRE_SEL) and slew rate control (3 levels via SLEW_CTL).
It integrates TMDS level translation, HDMI/DVI identification recognition, active DDC/I²C buffering, and failsafe HPD signaling. Device operation is configurable via either pin strapping (I2C_EN/PIN = low) or I²C interface (I2C_EN/PIN = high), with priority given to pin straps when both are active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 3.4 Gbps per lane - enables Ultra HD (4K × 2K / 30 Hz) and 1080p/60 Hz with 8-bit color depth. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade applications including docking stations and embedded video interfaces. |
| Power Consumption | 390 mW typical in 3.4-Gbps retimer mode; 10 mW in shutdown - supports thermal-constrained dongle PCBs. |
| Input Equalization | Adaptive or fixed (7.5 dB / 14 dB) - compensates for ISI jitter and loss from long cables or lossy board traces. |
| Output Compliance | HDMI 1.4b and DVI 1.0 TMDS electrical parameters - ensures interoperability with standard monitors and receivers. |
| Package | 40-pin WQFN, 0.4-mm pitch, 5.0 mm × 5.0 mm - surface-mount compatible with high-density GPU interface layouts. |
| Supply Voltages | VCC = 3.3 V ±10 %; VDD = 1.1 V ±17 % - dual-rail design separates analog TMDS output and digital core domains. |
Pinout & Package
SN65DP149RSBR uses a 40-pin WQFN package (5.0 mm × 5.0 mm, 0.4-mm pitch) with exposed thermal pad for enhanced thermal dissipation in compact dongle and motherboard applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_D0p/n to IN_D2p/n, IN_CLKp/n | Differential DP++ input lanes | Accepts AC-coupled DisplayPort dual-mode signals; supports fail-safe termination and intra-/inter-pair skew tolerance up to 112 ps / 1.8 ns. |
| OUT_D0p/n to OUT_D2p/n, OUT_CLKp/n | Differential TMDS output lanes | Drives HDMI/DVI-compliant outputs with adjustable swing (via VSADJ resistor), slew rate, and de-emphasis for cable/board loss compensation. |
| HPD_SRC / HPD_SNK | Hot-plug detect interface | OE-controlled bidirectional HPD signaling with 40–220 kΩ internal pull-down; propagation delay <120 ns. |
| SDA_SRC/SCL_SRC, SDA_SNK/SCL_SNK | DDC channel I/O | Failsafe bidirectional DDC lines supporting HDMI EDID read/write; compatible with 400-kHz fast-mode I²C. |
| OE, I2C_EN/PIN, EQ_SEL/A0, PRE_SEL, SLEW_CTL | Configuration control inputs | Three-level pin-strappable settings (L/NC/H) for equalization, de-emphasis, slew rate, and I²C enable - no external MCU required for basic setup. |
| VCC (pins 11, 37), VDD (pins 12, 19, 20, 31, 40) | Power supply rails | VCC powers TMDS output stage (3.3 V); VDD powers digital core and CDR (1.1 V); separate decoupling required per rail. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic retimer/redriver mode selection | Switches at 0.75–1.25 Gbps crossover threshold; eliminates manual configuration for mixed-data-rate source ecosystems. |
| Integrated CDR with 0.4–1 MHz PLL bandwidth | Reduces total output clock jitter to ≤0.25 Tbit at 297 MHz - meets HDMI 1.4b timing margin requirements. |
| Programmable TMDS output amplitude | Adjustable via external VSADJ resistor (6.5 kΩ nominal) - enables fine-tuning of 400–600 mV single-ended swing across process/voltage/temp. |
| Fail-safe DDC and HPD interfaces | Operates with VCC = 0 V; leakage current <45 µA on TMDS outputs and <40 µA on HPD_SNK - prevents false plug detection during power sequencing. |
| I²C-accessible register map | Full configuration control over equalization, de-emphasis, slew rate, and HDMI/DVI mode - enables dynamic adaptation in host-managed systems. |

FAQ
What is the operating temperature range of the SN65DP149RSBR?
The SN65DP149RSBR is rated for an industrial temperature range of –40°C to +85°C. This specification is validated per TI's production data sheet SLLSEL2C and applies across all electrical parameters including retimer jitter performance, equalization gain, and power supply current draw. The SN65DP149RSBR maintains full HDMI 1.4b TMDS compliance within this range without derating.
Does the SN65DP149RSBR support automatic switching between retimer and redriver modes?
Yes, the SN65DP149RSBR automatically switches between retimer and redriver modes based on input data rate: it operates as a redriver below 1.0 Gbps and as a retimer above that threshold, with a hysteresis band of 0.75–1.25 Gbps. This behavior is enabled by default and can be disabled via I²C register programming to force fixed-mode operation.
How is TMDS output voltage swing controlled on the SN65DP149RSBR?
The SN65DP149RSBR uses an external resistor connected from VSADJ pin to GND to set TMDS output swing. A 6.5-kΩ resistor yields nominal 500-mV single-ended swing; swing varies ±20 mV per 100-Ω change in VSADJ resistance. This adjustment directly impacts HDMI 1.4b compliance margin and must be validated per JEDEC JESD79-3E for TMDS output amplitude.
Can the SN65DP149RSBR be configured without an I²C master controller?
Yes, the SN65DP149RSBR supports full pin-strapped configuration via OE, I2C_EN/PIN, EQ_SEL/A0, PRE_SEL, SLEW_CTL, and HDMI_SEL/A1. With I2C_EN/PIN held low, all key functions - equalization mode, de-emphasis level, slew rate, and HDMI/DVI identification - are set using three-level (L/NC/H) logic states, eliminating need for external I²C firmware.
What is the maximum supported resolution and refresh rate for the SN65DP149RSBR?
The SN65DP149RSBR supports up to 3.4 Gbps per lane, enabling Ultra HD (3840 × 2160) at 30 Hz with 8-bit color depth, or Full HD (1920 × 1080) at 60 Hz with 16-bit color depth. These resolutions are achievable only when paired with a compliant DisplayPort 1.1a or later source and HDMI 1.4b sink - the SN65DP149RSBR itself does not perform format conversion or scaling.
