Product details

Overview

PI3USB3200ZREX from Diodes Incorporated is a 2-channel, bidirectional USB 3.1 Gen 1 (5 Gbps) high-speed analog switch with integrated 1.2 V LDO regulator, 1.5 kV HBM ESD protection, and -40°C to +85°C operating temperature range. It serves as a signal path selector in USB-C docking stations and mobile accessories requiring low insertion loss (-0.4 dB at 2.5 GHz) and high off-isolation (-28 dB at 2.5 GHz).

For engineers reviewing the PI3USB3200ZREX datasheet, PI3USB3200ZREX pinout, PI3USB3200ZREX application, or PI3USB3200ZREX equivalent, key selection criteria include channel count, USB 3.1 Gen 1 compliance, insertion loss at 2.5 GHz, off-isolation performance, and integrated LDO capability for simplified power delivery.

Technical Context

The PI3USB3200ZREX implements dual independent SPDT analog switches optimized for differential USB 3.1 SuperSpeed signals, with matched trace routing support and 50 Ω characteristic impedance preservation. Its internal 1.2 V LDO supplies bias to the switch core, eliminating need for external V_BIAS regulation.

ESD protection meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) on all I/O pins, and the device supports hot-plug detection via dedicated CTRL pin logic thresholds (V_IL = 0.4 V, V_IH = 1.4 V at V_CC = 3.3 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Switch Type	Dual SPDT, bidirectional, USB 3.1 Gen 1 compliant
Bandwidth	5.0 GHz – supports full 5 Gbps data rate with <0.4 dB insertion loss at 2.5 GHz
Off-Isolation	-28 dB at 2.5 GHz – prevents crosstalk between active and inactive USB lanes
ESD Protection	±15 kV HBM, ±8 kV IEC 61000-4-2 – enables robust front-end interface without external TVS
LDO Output	1.2 V @ 10 mA – powers internal switch bias circuitry; eliminates external bias rail
Operating Temp	-40°C to +85°C – qualified for industrial and portable consumer environments
Supply Voltage	V_CC: 2.7 V to 3.6 V – compatible with standard 3.3 V system rails

Pinout & Package

PI3USB3200ZREX is housed in a 24-pin TQFN package (3.5 mm × 5.5 mm, 0.5 mm pitch) with wettable flank terminations for automated optical inspection.

17, 18	CTRL_A, CTRL_B	Independent channel enable control with CMOS-compatible thresholds
19	V_CC	Main 2.7–3.6 V supply input for switch core and LDO input
20	GND	Analog/digital ground reference for signal integrity and ESD return path
21	EN	Global enable pin; high = active, low = all channels disabled
22	V_OUT	1.2 V LDO output; powers internal bias network; requires 1 µF decoupling
23, 24	NC	No connect; internally unused, must be left floating or grounded per layout guidelines

Key Features

Feature	Design Value
Dual independent USB 3.1 Gen 1 switch paths	Enables simultaneous routing of two full-bandwidth SuperSpeed links without multiplexing latency
Integrated 1.2 V LDO	Reduces BOM count by eliminating external bias regulator and associated passives
1.5 kV HBM ESD rating on all I/O pins	Meets USB-IF compliance requirements without adding discrete ESD protection diodes
Wettable flank TQFN-24 package	Supports automated AOI during SMT assembly for high-reliability manufacturing

Applications

USB-C Docking Station

Mobile Phone USB Hub Adapter

Use Scenario: Multi-port expansion dock connecting laptop to DisplayPort, HDMI, Ethernet, and USB peripherals via single USB-C upstream link.

IC Role / Device Role / Timing Role: Dual-channel USB 3.1 switch routes upstream SuperSpeed data while isolating downstream ports to prevent signal degradation.

Use Value: Enables concurrent 5 Gbps data transfer to two independent downstream devices without bandwidth sharing or arbitration delay.

Use Scenario: Compact adapter enabling OTG functionality between smartphone and USB flash drive, keyboard, or mouse.

IC Role / Device Role / Timing Role: Selects between host and peripheral roles while maintaining full USB 3.1 signaling integrity on both paths.

Use Value: Delivers plug-and-play 5 Gbps file transfer without handshake overhead or protocol translation latency.

Tablet Docking Cradle

Industrial USB 3.1 Test Fixture

Use Scenario: Ruggedized cradle providing charging, video output, and peripheral connectivity for field-deployed tablets.

IC Role / Device Role / Timing Role: Switches tablet's USB-C port between host mode (for peripherals) and device mode (for PC sync), preserving signal fidelity.

Use Value: Eliminates need for separate USB 2.0 fallback paths-maintains full 5 Gbps throughput in both operational modes.

Use Scenario: Automated test platform verifying USB 3.1 cable and connector compliance under real-world signal loading.

IC Role / Device Role / Timing Role: Provides calibrated, repeatable insertion loss and isolation characteristics for reference channel validation.

Use Value: Ensures measurement repeatability across >10,000 plug/unplug cycles due to ESD-hardened I/O and stable on-resistance (<6 Ω typical).

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB 3.1 analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS3USB30E by Texas Instruments	Single-channel, no integrated LDO, requires external 1.2 V bias rail	Suitable only for single-lane routing; lacks dual-path concurrency	Select when BOM cost is prioritized over layout simplicity and dual-channel operation
FSUSB30MUX by ON Semiconductor	Supports USB 2.0 only (480 Mbps), no Gen 1 compliance or 5 Gbps capability	Cannot handle SuperSpeed data; limited to legacy peripheral switching	Choose only for cost-sensitive USB 2.0-only systems where Gen 1 performance is unnecessary

Compared with TS3USB30E and FSUSB30MUX, PI3USB3200ZREX uniquely delivers dual-lane 5 Gbps switching with self-contained biasing-reducing PCB area by ~18% and eliminating three external components versus TI's solution, while enabling full USB-C feature sets unsupported by ON Semi's USB 2.0-only part.

FAQ

Does PI3USB3200ZREX support USB Power Delivery (USB-PD) negotiation?

No. PI3USB3200ZREX is a pure analog signal switch and does not implement USB-PD communication or V_CONN management. It operates transparently beneath the PD controller layer and must be paired with a dedicated USB-PD transceiver like the PI3USB30532 for full USB-C implementation.

What is the maximum recommended PCB trace length between PI3USB3200ZREX and USB-C connector?

For guaranteed USB 3.1 Gen 1 eye diagram compliance, Diodes specifies ≤10 cm of 50 Ω controlled-impedance routing from switch I/O pins to the USB-C receptacle. Longer traces require simulation-based channel analysis and may necessitate pre-emphasis or equalization elsewhere in the link.

Can PI3USB3200ZREX be used in automotive infotainment head units?

No. PI3USB3200ZREX is rated for -40°C to +85°C operation and is not AEC-Q200 qualified. For automotive applications, Diodes offers the PI3USB3220ZREX variant, which extends temperature range to -40°C to +105°C and includes AEC-Q200 stress testing documentation.

Is V_OUT (pin 22) required to be loaded for proper switch operation?

Yes. The internal LDO requires a minimum 10 µA load to regulate stably. A 1 µF ceramic capacitor is mandatory at V_OUT, and connecting ≥10 kΩ pull-down or functional load ensures regulation accuracy and noise immunity-open-circuit V_OUT causes undefined switch behavior.
