PI2USB4122ZHE

Analog Switches - Special Purpose Overview

The PI2USB4122ZHE is a 4-to-1 differential channel multiplexer/demultiplexer switch designed for USB 3.0 applications operating at 5.0 Gbps. It features a 42-contact TQFN package and operates on a single supply voltage of 1.8V ±10%. The device supports four selectable channels (A, B, C, D) controlled by SEL0 and SEL1 inputs. Key electrical parameters include a maximum bit-to-bit skew of 7 ps, a -3dB bandwidth of 2.6 GHz, and typical off-isolation of -25 dB at 2.5 GHz. Quiescent power supply current is typically 300 µA, with an operating temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Supports USB 3.0 signal switching at data rates up to 5.0 Gbps
• Provides low bit-to-bit skew for high-fidelity signal integrity
• Offers high channel-to-channel noise isolation and low crosstalk

Analog Switches - Special Purpose Applications

• Switching USB 3.0 signals for Mux or DeMux configurations

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation before procurement. The 'X' suffix indicates tape and reel packaging, while the 'E' suffix denotes lead-free and green material compliance. Confirm that the component matches the required 42-contact TQFN form factor and ensure compatibility with the intended 1.8V logic levels.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring USB 3.0 signal routing with minimal signal degradation. Ensure the design accommodates the specified 1.8V ±10% supply voltage and verify that the thermal characteristics of the TQFN package meet the system's dissipation requirements within the -40°C to +85°C operating range.
