PI3DBS12212AZBEX

Analog Switches - Special Purpose Overview

The PI3DBS12212AZBEX is a differential channel multiplexer/demultiplexer switch manufactured by Diodes Incorporated. It supports data rates up to 12 Gbps and operates with a supply voltage of 3.3V. The device features bi-directional operation, low bit-to-bit skew (1ps typ), and low channel-to-channel skew (7ps typ). Electrical performance includes a 3dB bandwidth of 10.6GHz, insertion loss of -1.5dB at 5 GHz, return loss of -19.6dB at 5 GHz, crosstalk of -30.5dB at 6 GHz, and off isolation of -17.1dB at 6 GHz. Power consumption is typically 200µA. It is housed in a 20-contact TQFN package and functions within an industrial temperature range of -40°C to 85°C.

Analog Switches - Special Purpose Feature Summary

• Supports high-speed differential signal routing for protocols including USB 3.0, USB 3.1, 10GE, Thunderbolt, and SAS 3.0
• Minimizes impedance and attenuation through unique design techniques targeting layout requirements
• Provides bi-directional switching capability with minimal channel-to-channel skew and crosstalk

Analog Switches - Special Purpose Applications

• Routing high-speed differential signals such as USB 3.0 and USB 3.1
• Signal switching for 10 Gigabit Ethernet (10GE) applications
• Thunderbolt interface signal management
• SAS 3.0 signal routing

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. The 'E' suffix indicates lead-free and green manufacturing compliant with RoHS directives. Confirm the 'X' suffix denotes tape and reel packaging if required for automated assembly processes. Ensure the component meets environmental standards relevant to the target deployment region.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring a 2:1 multiplexer/demultiplexer for differential lanes operating up to 12 Gbps. The 20-contact TQFN package is suitable for space-constrained layouts. Consider the low power consumption and ESD protection ratings for robust system integration. Verify that the 3.3V supply voltage aligns with the system's power architecture.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3DBS12212A product line from Diodes Incorporated. It is functionally similar to the PI3DBS12212AXUAEX, which utilizes an 18-contact X2QFN package instead of the 20-contact TQFN found in the AZBEX variant. Both parts share identical electrical specifications and application support for high-speed serial interfaces.

Analog Switches - Special Purpose Replacement Considerations

The PI3DBS12212AXUAEX serves as a direct package alternative within the same series. Verify pinout compatibility between the 20-contact TQFN and 18-contact X2QFN packages before substitution. No other cross-model replacements are confirmed in public documentation.
