PI3HDMI1210-ABE

Specialized Overview

The PI3HDMI1210-ABE is a high-performance HDMI signal switch manufactured by Diodes Incorporated (formerly Pericom Semiconductor). It functions as a bidirectional 2-to-1 multiplexer and demultiplexer for DVI/HDMI standards. The device supports four differential channels for high-speed data and two additional channels for side-band signals. It accommodates a maximum data rate of 4.0Gbps with a clock rate support up to 340MHz. The component operates on dual power supplies: VDD33 ranging from 3.0V to 3.6V, and VDD50 ranging from 4.2V to 5.5V. It utilizes a 48-pin BQSOP package.

Specialized Feature Summary

• Bidirectional switching capability for TMDS signals with minimal attenuation
• Integrated side-band signal support for DVI/HDMI control lines
• High channel-to-channel noise isolation and low bit-to-bit skew
• Built-in ESD protection rated at 12kV HBM for high-speed channels

Specialized Applications

• Sink-side switching in high-resolution video networks
• Switching between multiple sources for next-generation HDTV systems
• PC graphics peripheral connections requiring DVI/HDMI compliance

Specialized Procurement Notes

Verify the manufacturer origin, as the datasheet references Pericom Semiconductor while current branding is Diodes Incorporated. Confirm the specific ordering suffix 'B' corresponds to the 48-pin BQSOP package and that the 'E' suffix indicates Pb-free and Green status. Ensure compatibility with the required dual voltage rails (3.3V and 5.0V) during procurement planning.

Specialized Selection Notes

Select this component when designing sink-side switches for HDMI or DVI applications requiring bidirectional signal routing. It is suitable for systems needing to switch between multiple source inputs to a single display output. Verify that the design can accommodate the separate 3.3V and 5.0V power supply requirements specified in the datasheet.

Specialized Part Context

This part belongs to the PI3HDMI series of switch circuits designed for TMDS signal processing. Unlike modern redrivers or muxes found in newer HDMI 2.1 products, this device targets legacy DVI/HDMI standards with a 4.0Gbps data rate limit. It represents an earlier generation of interface ICs focused on basic signal routing rather than active equalization.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official cross-reference lists from Diodes Incorporated or verify pin-compatible alternatives specifically supporting 4.0Gbps HDMI/DVI switching.
