PI3DBS16222ZLEX

Analog Switches - Special Purpose Overview

The PI3DBS16222ZLEX is a differential exchange switch manufactured by Diodes Incorporated, operating at data rates up to 20Gbps. It features four differential channels configured as a 2x2 exchange switch with a pass-through pinout. The device supports bidirectional operation and functions within a VDD operating range of 3.3V ± 10%. It maintains an industrial temperature range from -40°C to +85°C. Key electrical parameters include a bit-to-bit skew of 10ps between positive and negative signals. Crosstalk performance reaches -30dB at 4.0GHz (8Gbps) and -19dB at 8.0GHz (16Gbps). Insertion loss is specified at -1.0dB at 4.0GHz, -1.5dB at 8.0GHz, and -2.0dB at 10GHz.

• Enables applications in PCI Express Gen 4, USB 3.1 Gen 2, Thunderbolt 3, and 10G BASE-KR standards.
• Features low insertion loss and minimal bit-to-bit skew for signal integrity preservation.

Analog Switches - Special Purpose Applications

• Server and storage systems utilizing PCIe Gen 4 interfaces
• PCs, notebooks, tablets, and all-in-one computers supporting USB 3.1 Gen 2 or Thunderbolt 3
• Embedded systems requiring USB 3.1 Gen 2 connectivity
• Network routers and switches implementing 10G BASE-KR

Analog Switches - Special Purpose Procurement Notes

Verify the specific package variant required for the design, as the PI3DBS16222 series is available in both ZL (TQFN) and XEA (X1QFN) packages. Confirm that the ordering suffix matches the desired reel configuration and lead-free compliance status. Ensure the selected component meets the RoHS 2 and RoHS 3 directives if environmental compliance is mandatory for the target market.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring a 20Gbps differential exchange switch with bidirectional capabilities. The choice depends on the required channel count and physical footprint constraints, as the ZL package offers 30 contacts while the XEA provides 24 contacts. Verify that the system operates within the specified 3.3V power supply tolerance and the -40°C to +85°C temperature range to ensure reliable performance.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3DBS16222 product line from Diodes Incorporated, designed for high-speed interface switching. The ZLEX suffix indicates the 30-contact TQFN package variant with lead-free and green packaging. It serves as a critical interconnect solution for modern high-bandwidth protocols, differentiating itself through low crosstalk and insertion loss specifications suitable for next-generation computing platforms.

Analog Switches - Special Purpose Replacement Considerations

The PI3DBS16222XEAEX is a direct alternative within the same family, offering identical electrical performance but housed in a 24-contact X1QFN package. When substituting, verify that the PCB footprint accommodates the different package dimensions and pinout layout changes between the TQZN and X1QFN variants.

Analog Switches - Special Purpose FAQ
