PI3USB302-AZBEX

Analog Switches - Special Purpose Overview

The PI3USB302-AZBEX is a USB switch IC featuring a 2:1 multiplexer/demultiplexer configuration for USB 3.0 SuperSpeed signals. It operates on a single 3.3V power supply (±10%) and supports bi-directional data transfer at 5.0 Gbps. The device utilizes a 20-contact, 2.5 × 4.5mm TQFN package with a center ground pad. Key electrical parameters include a maximum bit-to-bit skew of 10 ps, a 3dB bandwidth of 8.1 GHz, and low insertion loss of -1 dB at 2.5 GHz. It provides an ESD tolerance of 2 kV HBM and draws a typical operating current of 0.2 mA.

Analog Switches - Special Purpose Feature Summary

• Supports bi-directional switching of two differential channels for USB 3.0 SuperSpeed applications
• Provides high signal integrity through low bit-to-bit skew and minimal channel-to-channel noise isolation
• Features a compact surface-mount package designed for space-constrained routing solutions

Analog Switches - Special Purpose Applications

• Routing USB 3.0 SuperSpeed signals in host or device architectures
• Signal switching between multiple USB 3.0 ports and a common interface
