PI3V713-AZLEX

Analog Switches - Special Purpose Overview

The PI3V713-A is a 3.3V, 7-channel analog video switch designed for routing VGA signals between multiple sources or endpoints. It supports RGB, Hsync, Vsync, and DDC paths with a typical -3dB bandwidth of 1.7GHz. The device features a dual power supply configuration: a 3.3V rail (VDD) for the main switching matrix and a 5V rail (5V VDD) to drive horizontal and vertical sync outputs with ±24mA current capability. The DDC path functions as a level shifter between 5V and 3.3V domains. Key electrical parameters include an on-resistance (Ron) of 4.8Ω (typical), flatness of 0.5Ω, and input/output capacitance of 5.6pF. ESD tolerance reaches 12kV HBM.

Analog Switches - Special Purpose Feature Summary

• Provides seven dedicated channels for high-bandwidth analog video signal routing including RGB, synchronization, and DDC lines.
• Integrates a 5V to 3.3V level shifting mechanism within the DDC data and clock paths to support mixed-voltage system architectures.
• Features buffered H/V output drivers capable of sourcing and sinking ±24mA to maintain signal integrity over long traces.

Analog Switches - Special Purpose Applications

• Routing physical layer signals in notebook docking station environments where analog video ports exist on both the host and the dock.
• Switching between multiple VGA sources or display endpoints in high-bandwidth digital video systems.
• Protecting video interfaces against electrostatic discharge events while maintaining low signal attenuation.

Analog Switches - Special Purpose Procurement Notes

Verify that the ordering suffix matches the required packaging format. The 'ZLE' designation indicates a 32-contact TQFN package that is lead-free and green compliant. Confirm whether the specific part number variant includes tape and reel packaging by checking for an 'X' suffix at the end of the ordering code, as this affects handling and assembly procedures.

Analog Switches - Special Purpose Selection Notes

Select this component when a solution is required to switch between two distinct VGA port locations while preserving signal integrity across long FR4 traces. Ensure the design accommodates the dual power supply requirement, providing both a 3.3V rail for the core logic and a 5V rail for the synchronous output buffers. Verify that the SEL pin control logic aligns with the system's voltage levels, as inputs can be driven up to 3.6V regardless of the supply voltage.

Analog Switches - Special Purpose Part Context

This component belongs to the category of multiplexer switch ICs specifically optimized for analog video applications. Unlike general-purpose switches, it is engineered to handle the specific frequency responses and impedance matching requirements of VGA signals. The device integrates protection diodes to VDD and GND, distinguishing it from standard bus switches that may lack robust ESD handling capabilities for exposed video connectors.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement supports the same 7-channel architecture, dual voltage operation (3.3V/5V), and comparable bandwidth specifications to maintain compatibility with existing VGA signal routing designs.
