PI3DBS12412AZHE

Analog Switches - Special Purpose Overview

The PI3DBS12412AZHE is a 3.3V, 10-12Gbps 2-lane multiplexer/demultiplexer switch manufactured by Diodes Incorporated. It features four differential channels configured as a 2:1 mux/demux. The device supports data rates up to 12Gbps for SAS 3.0 applications and is compatible with Thunderbolt signaling at 10.3125Gbps, 10Gbps Ethernet, and USB 3.1. Key electrical parameters include a 3dB bandwidth of 11.3 GHz, low bit-to-bit skew of 1ps typical, and low channel-to-channel skew of 7ps typical. Insertion loss is -1.4dB at 5 GHz and -1.5dB at 6 GHz. Return loss measures -19.3dB at 5 GHz and -17.3dB at 6 GHz. Crosstalk is -30.5dB at 6 GHz, and off isolation is -17.1dB at 6 GHz. Typical power consumption is 400 μA. It operates within an industrial temperature range of -40°C to 85°C and offers 2KV HBM ESD protection. The component is available in a 42-contact TQFN (ZH42) package measuring 3.5x9mm.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 3.3V supply requirements and industrial temperature ranges during sourcing. Confirm RoHS compliance status through manufacturer datasheets prior to procurement.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring 2:1 multiplexing of differential pairs up to 12Gbps. Consider the 42-contact TQFN package for layout constraints. Evaluate thermal performance within the -40°C to 85°C operating range. Verify signal integrity requirements against the specified insertion loss and skew parameters.

Analog Switches - Special Purpose Part Context

The PI3DBS12412A belongs to Pericom's high-speed analog switch family, now under Diodes Incorporated. It addresses the need for flexible signal routing in modern high-bandwidth interfaces. The device integrates multiple differential channels into a compact solution suitable for space-constrained high-performance computing and storage systems.

Analog Switches - Special Purpose Replacement Considerations

Check for updated part numbers from Diodes Incorporated if Pericom branding is phased out. Verify pinout compatibility with existing PCB layouts when substituting similar mux/demux switches from other manufacturers.
