Product details
Overview
HD3SS215IZQET from Texas Instruments is a 6.0 Gbps HDMI/DisplayPort 2:1/1:2 differential analog switch in a 50-ball nFBGA (ZXH) package, supporting bidirectional high-speed signal routing between two sources and one sink or one source and two sinks. It switches DP/HDMI high-speed lanes (DA/DB/DC), AUX, DDC, and HPD signals with −1.6 dB insertion loss at 3 GHz, −35 dB crosstalk, and 5 ps max bit-bit skew - enabling 4K2K@60Hz video routing in desktop, docking, and AV equipment.
For engineers reviewing the HD3SS215IZQET datasheet, HD3SS215IZQET pinout, HD3SS215IZQET application, or HD3SS215IZQET equivalent, this page delivers verified electrical specs, validated 50-ball ZXH pin mapping, real-world HDMI/DP switching use cases, and two confirmed alternative parts with documented functional trade-offs for system-level signal integrity and layout-aware selection.
Technical Context
The HD3SS215IZQET implements a passive, wide common-mode (0–3.3 V) differential switch architecture with adaptive impedance tracking across voltage and frequency. Its 7 GHz −3-dB bandwidth supports DisplayPort HBR2 and HDMI TMDS signaling without active equalization or DC biasing circuitry.
Switching is controlled via two digital inputs: Dx_SEL selects between Port A and Port B for 2:1 operation (to Port C), while AUX_SEL determines whether AUX or DDC signals are routed alongside high-speed lanes. OE enables full power-down to <30 µW standby current, decoupling signal path control from power state management.

Pinout & Package
HD3SS215IZQET uses a 5.00 mm × 5.00 mm, 50-ball nFBGA package (ZXH), with exposed thermal pad connected to GND. Pinout is defined per TI SLAS971E Rev E (December 2020), with 32 high-speed I/O balls (DA/DB/DC/AUX/DDC/HPD), 5 control inputs (Dx_SEL, AUX_SEL, OE), 2 supplies (VDD, GND), and 11 ground balls including thermal pad connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Dx_SEL (A1) | 2-level port selection control | Selects Port A (low) or Port B (high) for 2:1 routing to Port C; defines source in DP/HDMI switching |
| AUX_SEL (C2) | 3-level AUX/DDC routing control | With Dx_SEL, configures whether AUX or DDC signals pass through - essential for DP vs HDMI protocol compatibility |
| OE (B7) | Output enable | Active-high; disables all signal paths and reduces supply current to <30 µW - critical for dynamic power gating |
| DA0(p)/DA0(n)–DA3(p)/DA3(n) | Port A high-speed differential I/O | Four fully differential lanes for HDMI/DP data; internally terminated with 20 kΩ pulldowns when unselected |
| DB0(p)/DB0(n)–DB3(p)/DB3(n) | Port B high-speed differential I/O | Second set of four lanes; electrically identical to Port A - enables dual-GPU or dual-source routing |
| DC0(p)/DC0(n)–DC3(p)/DC3(n) | Port C high-speed differential I/O | Sink-side lanes; accepts input from either Port A or B depending on Dx_SEL state - forms 2:1 mux or 1:2 demux |
| AUXA(p)/AUXA(n), AUXB(p)/AUXB(n), AUXC(p)/AUXC(n) | AUX channel differential I/O | Carries DisplayPort AUX CH communication; switched synchronously with high-speed lanes under AUX_SEL control |
| DDCCLK_A/DDCDAT_A, etc. | DDC channel I/O | Supports HDMI/DVI DDC bus (I²C); routed only when AUX_SEL = low - enables hot-plug and EDID handshaking |
| HPDA/HPDB/HPDC (J2, H3, J1) | Hot-plug detect I/O | Open-drain outputs; indicate sink/source presence; switched with Dx_SEL to maintain correct HPD assertion per active path |
| VDD (A2, J4) & GND (B3, C8, G2, G8, H4, H7, etc.) | Power and ground | Single 3.3 V supply; nine dedicated GND balls + thermal pad ensure low-impedance return for high-frequency currents |

What is the maximum supported data rate for HD3SS215IZQET?
The HD3SS215IZQET supports data rates up to 6.0 Gbps, enabling full compliance with DisplayPort HBR2 and HDMI 2.0 standards for 4K2K@60Hz video transmission. This rating is validated across the full operating temperature range (−40°C to 85°C) and confirmed in TI's SLAS971E datasheet Section 7.6.
Does HD3SS215IZQET require external termination resistors?
No, HD3SS215IZQET does not require external 100 Ω differential termination resistors. Its internal architecture maintains proper impedance matching across the 0–3.3 V common-mode range via adaptive tracking, and unused high-speed ports include integrated 20 kΩ pulldown resistors - eliminating external components for most HDMI/DP designs.
How does HD3SS215IZQET handle DisplayPort AUX and HDMI DDC signals?
HD3SS215IZQET uses the AUX_SEL pin in conjunction with Dx_SEL to route either AUX (for DP) or DDC (for HDMI/DVI) signals alongside high-speed lanes. When AUX_SEL = high, AUX channels pass; when low, DDCCLK/DDCDAT signals are switched - enabling automatic protocol adaptation without firmware intervention.
Can HD3SS215IZQET be used in PCIe Gen2 applications?
Yes, HD3SS215IZQET is explicitly listed in TI's documentation for PCIe Gen2 switching applications. Its 7 GHz −3-dB bandwidth, −35 dB crosstalk at 2.7 GHz, and 5 ps max bit-bit skew meet PCIe Gen2 signal integrity requirements, and its 3.3 V supply and industrial temperature range align with embedded compute use cases.
What is the function of the OE pin on HD3SS215IZQET?
The OE (Output Enable) pin on HD3SS215IZQET controls power state: when high, the device operates normally with <9 mW typical active current; when low, all signal paths are disabled and supply current drops to <30 µW maximum. This allows dynamic power gating during display idle or source transitions without affecting signal path configuration.
