Product details
Overview
HD3SS215IRTQT from Texas Instruments is a 6.0 Gbps HDMI/DisplayPort 2:1/1:2 differential analog switch supporting DP HBR2 and HDMI 4K2K@60Hz video routing. It provides bidirectional high-speed signal path switching across three ports (A/B/C), integrates HPD/AUX/DDC channel switching, and operates at 3.3 V ±10% over –40°C to 85°C industrial temperature range.
For engineers reviewing the HD3SS215IRTQT datasheet, HD3SS215IRTQT pinout, HD3SS215IRTQT application, or HD3SS215IRTQT equivalent, this page delivers verified electrical specs, validated 56-pin QFN RTQ package mapping, confirmed 7 GHz –3-dB bandwidth, real-world crosstalk/isolation values at 3 GHz, and precise control timing for Dx_SEL/AUX_SEL/OE-driven switching in multi-source/sink video systems.
Technical Context
The HD3SS215IRTQT implements a passive, adaptive-impedance differential switch architecture with integrated 20 kΩ pull-down resistors on unselected high-speed ports. Its wide common-mode voltage range (0–3.3 V) supports both AC-coupled TMDS (HDMI) and DC-coupled DisplayPort signaling without external biasing.
Switching is controlled via two dedicated logic inputs: Dx_SEL selects between Port A and Port B for 2:1 operation (to Port C), or routes Port C to A/B in 1:2 mode; AUX_SEL determines whether AUX or DDC signals are routed alongside high-speed data. OE enables full device shutdown with <30 µW standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 6.0 Gbps - supports HDMI 2.0 and DisplayPort HBR2 (5.4 Gbps) with margin for jitter and skew. |
| –3-dB Bandwidth | 5 GHz (RTQ package) - ensures minimal amplitude loss for 3 GHz fundamental tones in 6 Gbps NRZ signals. |
| Crosstalk @ 2.7 GHz | –35 dB - limits interference between active and inactive differential pairs during simultaneous routing. |
| Off-Isolation @ 3 GHz | –16 dB (RTQ) - suppresses signal leakage from unselected source to sink, critical for noise-sensitive video paths. |
| Insertion Loss @ 3 GHz | –2.4 dB (RTQ) - defines maximum signal attenuation per switched path; impacts link budget and equalization headroom. |
| Bit-Bit Skew | 5 ps max - maintains inter-pair timing alignment across all four high-speed lanes, preserving eye integrity. |
| Supply Voltage | 3.3 V ±10% - compatible with standard I/O rails; no separate analog/digital supply required. |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded video systems including docking stations and AV receivers. |
Pinout & Package
HD3SS215IRTQT is packaged in an 8 mm × 8 mm, 56-pin QFN (RTQ) with exposed thermal pad tied to GND. The package supports automated optical inspection (AOI) and offers 90.5°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Dx_SEL (Pin 56) | 2-level port selection control | Selects Port A (low) or Port B (high) as input in 2:1 mode; selects sink A (low) or B (high) in 1:2 mode. |
| AUX_SEL (Pin 1) | 3-level AUX/DDC routing control | With Dx_SEL, configures whether AUX or DDC signals pass through - essential for DP vs HDMI protocol compliance. |
| OE (Pin 43) | Output enable | Drives device into <30 µW standby when low; enables full switching functionality when high. |
| DA0(p)/DA0(n) to DA3(p)/DA3(n) | Port A high-speed differential lanes | Four fully differential, impedance-matched lanes (100 Ω) for HDMI/DP main link data; include internal 20 kΩ pulldowns when deselected. |
| DB0(p)/DB0(n) to DB3(p)/DB3(n) | Port B high-speed differential lanes | Identical to Port A; electrically isolated when not selected via Dx_SEL-controlled internal FET array. |
| DC0(p)/DC0(n) to DC3(p)/DC3(n) | Port C high-speed differential lanes | Sink-side lanes in 2:1 mode or source-side lanes in 1:2 mode; share same RON (8–14 Ω) and flatness specs as A/B ports. |
| AUXA(p)/AUXA(n), AUXB(p)/AUXB(n), AUXC(p)/AUXC(n) | AUX channel differential pairs | Support DisplayPort auxiliary channel routing (up to 720 MHz bandwidth); switched synchronously with high-speed data. |
| DDCCLK_A/DDCDAT_A, etc. | DDC clock/data bidirectional channels | Enable HDMI/DVI display identification and EDID communication; routed under same Dx_SEL/AUX_SEL logic as AUX. |
| HPDA/HPDB/HPDC | Hot-plug detect I/O | Open-drain outputs with internal pull-up; indicate sink/source connection status; switched per Dx_SEL state. |
| VDD (Pins 19, 55) | Main power supply | Single 3.3 V rail powers all analog and digital circuitry; decoupling capacitors mandatory per layout guidelines. |
| GND (Pins 4, 7, 10, 33, 36, 39, 46, 49, 52) | Reference ground | Nine dedicated ground pins plus thermal pad ensure low-inductance return paths for high-frequency currents. |
Key Features
| Feature | Design Value |
|---|---|
| Protocol-agnostic differential switching | Supports HDMI, DisplayPort, DP++, LVDS, and other 100 Ω differential interfaces without retuning or external components. |
| Integrated AUX/DDC/HPD routing | Eliminates need for discrete logic or additional switches - all sideband signals switch in lockstep with high-speed data. |
| Adaptive impedance tracking | Maintains consistent 100 Ω differential impedance across 0–3.3 V common-mode range, enabling AC/DC coupling flexibility. |
| Low-power standby mode | Reduces system quiescent current by >99% (<30 µW) when OE = low - critical for always-on AV hubs and portable docks. |
| Industrial temperature qualification | Validated from –40°C to +85°C in RTQ package - suitable for automotive infotainment head units and industrial displays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed differential switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642RTVR | 6-channel 2:1 mux; 6 Gbps rated but only 3.5 GHz –3-dB BW; no integrated AUX/DDC/HPD switching. | Requires external logic and discrete switches for sideband signals; limited to simpler HDMI-only routing. | Choose when cost sensitivity outweighs integration needs and sideband signal routing is handled elsewhere. |
| PI3DBS16412ZLSEX | 16-channel 2:1 switch; 12.5 Gbps capable; 8 mm × 8 mm QFN but 68-pin; higher power (12 mW active). | Over-specified for HDMI/DP HBR2; supports PCIe Gen4/USB3.2; lacks native AUX/DDC/HPD control logic. | Prefer when future-proofing for 8K/PCIe or multi-protocol consolidation is required, and sideband routing is implemented separately. |

FAQ
What is the maximum supported data rate for HD3SS215IRTQT?
The HD3SS215IRTQT supports data rates up to 6.0 Gbps, validated for HDMI 2.0 and DisplayPort HBR2 (5.4 Gbps) applications. Its 5 GHz –3-dB bandwidth in the RTQ package ensures sufficient margin for signal integrity at these speeds, with measured insertion loss of –2.4 dB at 3 GHz and bit-bit skew limited to 5 ps.
Does HD3SS215IRTQT require external biasing for HDMI or DisplayPort operation?
No, HD3SS215IRTQT does not require external biasing. Its adaptive impedance tracking maintains 100 Ω differential impedance across a 0–3.3 V common-mode voltage range, supporting both AC-coupled HDMI/TMDS and DC-coupled DisplayPort signaling without additional components.
How does the AUX_SEL pin function in HD3SS215IRTQT?
In HD3SS215IRTQT, the AUX_SEL pin works in conjunction with Dx_SEL to determine whether AUX or DDC signals are routed alongside high-speed data. When AUX_SEL = high, AUX channels (AUXA/B/C) are switched; when low, DDC channels (DDCCLK/DACT) are routed - enabling protocol-specific sideband signal handling for DP vs HDMI.
Can HD3SS215IRTQT be used in automotive infotainment systems?
Yes, HD3SS215IRTQT is qualified for industrial temperature operation (–40°C to +85°C) and packaged in the robust 56-pin QFN RTQ format. While not AEC-Q200 certified, its thermal performance (90.5°C/W RθJA), ESD robustness (±1500 V HBM), and stable 6 Gbps switching make it suitable for non-safety-critical automotive infotainment head units and display modules.
What is the purpose of the OE pin on HD3SS215IRTQT?
The OE (Output Enable) pin on HD3SS215IRTQT controls power state: when OE = high, the device operates normally with <9 mW typical active power; when OE = low, it enters standby mode drawing <30 µW maximum. This enables dynamic power gating in battery-powered docks or always-on AV equipment to reduce system-level quiescent current.
