Product details
Overview
PI3USB31532ZLCEX from Diodes Incorporated is a 10 Gbps 6:4 differential channel bi-directional crossbar switch for USB 3.1 Gen2 (10 Gbps) and DisplayPort 1.4 (8.1 Gbps) signal routing through USB Type-C connectors. It supports configurable routing of 1× USB 3.1 Gen2 lane plus 2× DP 1.4 channels, or 4× DP 1.4 lanes, with integrated AUX/HPD switching. Used in docking stations and notebooks for high-fidelity signal multiplexing.
For engineers reviewing the PI3USB31532ZLCEX datasheet, PI3USB31532ZLCEX pinout, PI3USB31532ZLCEX application, or PI3USB31532ZLCEX equivalent, key selection criteria include -38 dB crosstalk at 10 Gbps, 8.3 GHz -3 dB bandwidth, -15 dB return loss, 0.35 mA active supply current, and TQFN-40 (3×6 mm) package compatibility with USB Type-C system layouts.
Technical Context
The PI3USB31532ZLCEX implements a fully differential, bidirectional 6-input × 4-output analog crosspoint matrix with independent control of each path. Its architecture supports simultaneous switching of high-speed USB and DP lanes without protocol awareness, relying on passive analog signal integrity performance rather than embedded logic or packet inspection.
All six differential inputs (including two USB 3.1 Gen2 pairs and four DP 1.4 pairs) and four differential outputs are DC-coupled, with internal 50 Ω termination enabled only on selected paths during active routing. AUX and HPD signals are routed separately via dedicated single-ended switches with level-shifting capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed analog crossbar switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB3031RSER | 3:1 USB 3.0-only switch; 5 Gbps max; no DP support; smaller 16-pin QFN | Limited to single-lane USB 3.0; cannot route DP 1.4 or multi-lane configurations | Select only for cost-sensitive USB-only designs with ≤5 Gbps requirement |
| PI3DBS16412ZLEX | 16:12 DP 1.4-only switch; no USB 3.1 Gen2 support; higher channel count but no AUX/HPD integration | Requires external AUX/HPD switching; suited for pure display-centric systems | Choose when routing ≥3 DP 1.4 streams without USB coexistence |

FAQ
Does PI3USB31532ZLCEX require configuration registers or I²C control?
No. The PI3USB31532ZLCEX is a purely analog, pin-strapped crossbar switch with no embedded logic or serial interface. Routing is controlled by four digital select inputs (S0–S3), allowing static or GPIO-driven path configuration without firmware overhead or initialization sequence.
Can PI3USB31532ZLCEX support USB-C Alternate Mode negotiation?
No. This device operates at the physical layer only and does not participate in USB-C Alternate Mode handshaking (e.g., DisplayPort Alt Mode discovery via VCONN or SOP packets). It routes signals after mode negotiation is completed by the host controller and port manager.
What is the maximum junction temperature rating for continuous operation?
The PI3USB31532ZLCEX is rated for continuous operation up to +85°C ambient with standard PCB copper pour (2 oz, 2-layer). Thermal characterization data confirms junction temperature remains ≤115°C under full 10 Gbps loading with 0.35 mA supply current and recommended layout.
Is the TQFN-40 package RoHS and REACH compliant?
Yes. The PI3USB31532ZLCEX in ZLC tape-and-reel packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature type solders used in die attach. Certificate of Compliance is available from Diodes Incorporated upon request.
