PI2DBS212ZHE

Analog Switches - Special Purpose Overview

The PI2DBS212ZHEX is a differential broadband signal switch manufactured by Diodes Incorporated, originally designed by Pericom Semiconductor. It functions as a 2:1 multiplexer/demultiplexer with two differential channels and operates within a supply voltage range of 1.2V to 1.8V ±10%. The device supports data rates up to 3Gbps and features a 2.0 GHz bandwidth at -3dB when operating at 1.8V. Key electrical specifications include a maximum bit-to-bit skew of 5 ps, crosstalk of -26dB at 3.2 Gbps, and off-isolation of -35dB at 3.2 Gbps. It is housed in a 28-contact TQFN package.

Analog Switches - Special Purpose Feature Summary

• Supports SAS, SATA2, XAUI, Infiniband, HyperTransport, and Rapid I/O standards
• Provides low bit-to-bit skew for high-speed signal integrity
• Features low crosstalk and high off-isolation performance
• Includes ESD protection rated at 8kV HBM on I/O pins

Analog Switches - Special Purpose Applications

• Computer systems requiring high-speed data routing
• Consumer electronics utilizing SAS or SATA interfaces
• Instrumentation equipment needing differential signal switching

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm the specific ordering suffix matches the required tape and reel packaging configuration. Ensure compliance with RoHS standards and lead-free requirements before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring bidirectional differential signal routing between two sources and one receiver. Consider the 1.8V operating voltage and ensure the system design accommodates the specified quiescent current levels. Verify that the 28-contact TQFN package dimensions fit the target PCB layout constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the PI2DBS series of differential broadband switches. It is functionally related to other Pericom/Diodes Incorporated mux/demux devices like the PI2PCIE212 but is optimized for SAS/SATA/XAUI protocols rather than PCI Express. The ZHEX suffix indicates a Pb-free, green compliant version packaged in tape and reel format.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements may include the PI2DBS412 for four-channel applications or the PI2PCIE212 for PCI Express-specific designs. Verify pin compatibility and electrical characteristics against the original datasheet before substitution.
