Product details
Overview
HD3SS215IRTQR from Texas Instruments is a 6.0 Gbps HDMI/DisplayPort 2:1/1:2 differential analog switch IC for high-speed video routing, supporting DP HBR2 and HDMI 4K2K@60Hz, with 7 GHz –3-dB bandwidth, <1.6 dB insertion loss at 3 GHz, and 5 ps max bit-bit skew. It enables source-to-sink or sink-to-source switching in desktop GPU multiplexing and docking station applications.
For engineers reviewing the HD3SS215IRTQR datasheet, HD3SS215IRTQR pinout, HD3SS215IRTQR application, or HD3SS215IRTQR equivalent, key selection criteria include differential bandwidth (7 GHz), HPD/AUX/DDC co-switching capability, OE-controlled standby power (<30 µW), and compatibility with both HDMI and DisplayPort electrical standards across commercial and industrial temperature ranges.
Technical Context
The HD3SS215IRTQR implements a passive, wide common-mode (0–3.3 V) differential switch architecture with adaptive impedance tracking, enabling transparent signal routing without DC bias or level-shifting. Its 2:1/1:2 bidirectional topology supports either two sources to one sink (e.g., dual GPUs → single DP display) or one source to two sinks (e.g., laptop → dock or side port).
Switching is controlled via Dx_SEL (high-speed path selection) and AUX_SEL (AUX/DDC path selection), with independent HPD routing per port and OE-driven power gating. All high-speed channels (DAz/DBz/DCz) integrate 20 kΩ switched pull-down resistors active only on unselected ports to maintain signal integrity during idle states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 6.0 Gbps - Supports HDMI 4K2K@60Hz and DisplayPort HBR2 link rates without retiming. |
| –3-dB Bandwidth | 7 GHz (ZXH package) - Ensures minimal amplitude loss and phase distortion for full-bandwidth HDMI/DP signals. |
| Insertion Loss | –1.6 dB at 3 GHz - Maintains signal eye opening and jitter margin in high-speed serial links. |
| Crosstalk | –35 dB at 2.7 GHz - Prevents interference between active and inactive differential pairs during simultaneous operation. |
| Isolation | –21 dB at 3 GHz - Blocks signal leakage from selected to unselected paths, critical for noise-sensitive sink devices. |
| Supply Voltage | 3.3 V ±10% - Compatible with standard I/O rails; no external LDO required for core logic or biasing. |
| Power Consumption | <9 mW active / <30 µW standby - Enables low-power mode activation via OE pin without system-level voltage rail changes. |
Pinout & Package
HD3SS215IRTQR is packaged in an 8 mm × 8 mm, 56-pin QFN (RTQ) with exposed thermal pad tied to GND. Pin count and layout match TI's documented RTQ footprint; all signal pins are assigned per datasheet Figure 6-2 and Table 6-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Dx_SEL (Pin 56) | High-speed port selection control | Selects between Port A and Port B for 2:1 mode, or routes Port C to A/B in 1:2 mode; TTL-compatible input. |
| AUX_SEL (Pin 1) | AUX/DDC path selection control | Configures whether AUX or DDC signals are routed alongside high-speed data; used with Dx_SEL for full protocol switching. |
| OE (Pin 43) | Output enable | Active-high control: OE = VIH enables signal path; OE = VIL places all I/Os in high-Z standby, reducing current to <30 µW. |
| DA0(p)/DA0(n)–DA3(p)/DA3(n) | Port A high-speed differential lanes | Four fully differential TMDS/DP lanes (Ch 0–3); support AC- or DC-coupled links with 0–3.3 V common-mode range. |
| DB0(p)/DB0(n)–DB3(p)/DB3(n) | Port B high-speed differential lanes | Four fully differential lanes mirroring Port A; electrically identical and interchangeable in 2:1 configuration. |
| DC0(p)/DC0(n)–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 AUX CH signaling (up to 720 MHz bandwidth); integrated 5–8 Ω ON resistance ensures low-loss DDC/AUX routing. |
| DDCCLK_A/DDCDAT_A, etc. | DDC clock/data I/O | Bi-directional I²C-compatible DDC paths for HDMI/DVI; 30–40 Ω ON resistance preserves rise/fall times per HDMI spec. |
| HPDA/HPDB/HPDC | Hot-plug detect I/O | Open-drain outputs with internal pull-up; routed through Dx_SEL to maintain sink-side HPD state awareness during switching. |
| VDD (Pins 19, 55) | Main power supply | Single 3.3 V rail powers all logic and analog switch elements; decoupling capacitors must be placed per layout guidelines. |
| GND (Pins 4, 7, 10, 33, 36, 39, 46, 49, 52) | Ground reference | Multiple dedicated GND pins + thermal pad (tied to GND) ensure low-inductance return paths for high-frequency currents. |
