PI3DBS16213ZLEX

Analog Switches - Special Purpose Overview

The PI3DBS16213ZLEX is a differential channel multiplexer and demultiplexer switch manufactured by Diodes Incorporated. It supports data rates up to 20 Gbps for high-speed signals including USB3.0, USB3.1, 10GE, PCIe4, Thunderbolt 3, and SAS3.0. The device features a 2-channel, 3:1 configuration with bi-directional operation. Key electrical parameters include a 3dB bandwidth of 12 GHz, low bit-to-bit skew (3 ps typ), and low channel-to-channel skew (10 ps typ). Insertion loss is specified at -1.2 dB @ 5 GHz, -2 dB @ 8 GHz, and -2.9 dB @ 10 GHz. Return loss values are -20 dB @ 2.5 GHz, -18 dB @ 4.0 GHz, -16 dB @ 5 GHz, -9 dB @ 8 GHz, and -6 dB @ 10 GHz. Power consumption is typically 300 µA at a supply voltage of 3.3 V. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 30-contact TQFN package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. The ZLEX suffix indicates a 30-contact TQFN package in tape and reel format. Confirm RoHS compliance status and lead-free green material definitions against current manufacturer documentation before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring a 2-channel, 3:1 mux/demux solution for signals up to 20 Gbps. Ensure the design accommodates the 3.3V supply requirement and the -40°C to +85°C operating temperature range. Consider the 30-contact TQFN footprint dimensions of 2.5x4.5mm during PCB layout planning.

Analog Switches - Special Purpose Part Context

The PI3DBS16213 belongs to the PI3DBS16213 series of multiplexer switches from Diodes Incorporated. This series includes variants like the PI3DBS16213XEAEX, which utilizes a 24-contact X1QFN package. The family is designed for high-speed signal switching with minimized impedance and skew characteristics suitable for modern interface standards.

Analog Switches - Special Purpose Replacement Considerations

The PI3DBS16213XEAEX is a direct alternative within the same series, offering identical functional specifications but packaged in a 24-contact X1QFN form factor instead of the 30-contact TQFN found in the ZLEX variant. Verify pinout compatibility and thermal requirements when substituting packages.
