Product details
Overview
HD3SS215IZQER from Texas Instruments is a 6.0 Gbps HDMI/DisplayPort 2:1/1:2 differential analog switch supporting dual-directional high-speed signal routing between two sources and one sink or one source and two sinks. It integrates HPD, AUX, and DDC switching with 7 GHz –3-dB bandwidth, –35 dB crosstalk at 3 GHz, and 5 ps max bit-bit skew - enabling 4K2K@60Hz video routing in desktop, docking, and AV receiver systems.
For engineers reviewing the HD3SS215IZQER datasheet, HD3SS215IZQER pinout, HD3SS215IZQER application, or HD3SS215IZQER equivalent, key selection criteria include its dual-mode (2:1/1:2) configuration, 3.3 V operation, industrial temperature range (–40°C to 85°C), nFBGA ZXH package compatibility, and support for DP HBR2 and HDMI electrical standards without AC coupling constraints.
Technical Context
The HD3SS215IZQER implements a passive, wide common-mode (0–3.3 V) differential switch architecture with adaptive impedance tracking across voltage and frequency. Its 2:1/1:2 topology enables bidirectional routing of four high-speed differential pairs per port (DA/DB/DC), plus dedicated AUX and DDC channels controlled jointly by Dx_SEL and AUX_SEL pins.
Signal integrity is maintained via matched on-resistance (ΔRON ≤ 1.5 Ω), flat insertion loss (–1.6 dB @ 3 GHz), and low inter-pair skew (≤30 ps). The OE pin enables full power-down (<30 µW standby), while internal 20 kΩ pulldowns on unselected high-speed ports prevent floating nodes and ensure robust hot-plug detection behavior.

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 |
|---|---|---|---|
| TS3DV642RHBT | 6-channel 2:1 mux; 6 Gbps rated but only 5.5 GHz bandwidth; no integrated AUX/DDC switching | Requires external logic for HPD/AUX routing; limited to simpler HDMI-only systems without DP++ support | Preferred where cost sensitivity outweighs protocol flexibility and board space allows discrete support components |
| PI3DBS16412ZDE | 16-channel 2:1 switch; 10 Gbps capable; supports PCIe Gen4 but lacks native DDC/HPD pins | Targeted at server/storage interconnects; not optimized for consumer video protocols or hot-plug signaling | Applicable only in non-HDMI/DP contexts where ultra-high bandwidth and channel count supersede protocol integration |
Compared with TS3DV642RHBT and PI3DBS16412ZDE, HD3SS215IZQER uniquely combines HDMI/DP protocol-aware switching (AUX/DDC/HPD), industrial temperature rating, and compact ZXH packaging - making it the only drop-in solution for embedded docking, GPU switching, and AV receiver designs requiring full compliance without external glue logic.

FAQ
What is the maximum supported data rate for HD3SS215IZQER?
The HD3SS215IZQER supports data rates up to 6.0 Gbps, validated for HDMI 2.0 and DisplayPort HBR2 applications. This enables transmission of uncompressed 4K2K video at 60 Hz refresh rate with full color depth, meeting the bandwidth requirements of modern high-resolution displays and graphics subsystems. The device achieves this with measured insertion loss of –1.6 dB at 3 GHz and 7 GHz –3-dB differential bandwidth in the ZXH package.
Does HD3SS215IZQER support both HDMI and DisplayPort protocols simultaneously?
HD3SS215IZQER does not process or interpret HDMI or DisplayPort protocols - it is a passive analog switch. However, its wide common-mode range (0–3.3 V), 7 GHz bandwidth, and integrated AUX/DDC/HPD switching make it compatible with both HDMI and DP electrical standards. System-level protocol compliance depends on correct configuration of Dx_SEL and AUX_SEL pins per application mode, as defined in the TI datasheet for HD3SS215IZQER.
What is the function of the OE pin on HD3SS215IZQER?
The OE (Output Enable) pin on HD3SS215IZQER is an active-high control that enables normal switching operation when driven high (VIH ≥ 2 V), and places all high-speed, AUX, DDC, and HPD I/Os into high-impedance state when pulled low. In standby mode (OE = L), HD3SS215IZQER draws less than 30 µW, reducing system power consumption significantly - a key advantage in battery-powered docking solutions and always-on AV equipment.
Which package type does HD3SS215IZQER use, and what are its key mechanical features?
HD3SS215IZQER uses the 5.00 mm × 5.00 mm, 50-ball nFBGA package designated ZXH. It features an exposed thermal pad connected to GND for enhanced heat dissipation, nine ground balls for low-inductance return paths, and footprint compatibility with legacy MicroStar Jr. BGA packages. The ZXH variant delivers superior RF performance versus the larger 56-pin QFN RTQ option, with higher bandwidth (7 GHz vs 5 GHz) and lower crosstalk (–35 dB).
How does HD3SS215IZQER handle hot-plug detection (HPD) in HDMI and DisplayPort configurations?
HD3SS215IZQER routes HPD signals bi-directionally across all three ports (HPDA, HPDB, HPDC) under control of the Dx_SEL pin. In 2:1 mode, HPD from the selected source passes through to the sink; in 1:2 mode, HPD from the source is duplicated to both sinks. Internal 20 kΩ pulldowns on unselected ports ensure clean HPD state transitions during plug/unplug events - a critical requirement for reliable EDID negotiation and display enumeration in HD3SS215IZQER-based systems.
