PI3WVR12412ZHE

Analog Switches - Special Purpose Overview

The PI3WVR12412ZHE is a wide voltage range DisplayPort and HDMI video switch manufactured by Diodes Incorporated. It supports DisplayPort 1.2, HDMI 1.4, and proprietary standards with four high-speed lanes configured as a 1:2 mux/demux. The device handles signals up to 1.2 V peak-to-peak differential with common-mode voltages from 0 to 3.4V, enabling DC-coupled operation. Key electrical parameters include -1.6 dB insertion loss at 2.7 GHz, a 4.6 GHz -3 dB bandwidth, and low channel-to-channel skew of 35 ps maximum. It also switches AUX and HPD signals, supporting 720 Mbps DP AUX communication.

Analog Switches - Special Purpose Feature Summary

• Supports multi-standard video switching for DisplayPort 1.2 and HDMI 1.4 with wide voltage range capability
• Enables DC-coupled operation to eliminate AC coupling capacitors and save board space
• Integrates dedicated switching for HPD and differential AUX signals alongside high-speed data lanes

Analog Switches - Special Purpose Applications

• Routing DisplayPort and HDMI signals between source and sink devices
• High-definition television (HDTV) signal distribution
• Flat panel display interfaces requiring low signal attenuation

Analog Switches - Special Purpose Procurement Notes

Verify the component authenticity through official Diodes Incorporated channels or authorized distributors. Confirm the specific ZHE suffix corresponds to the 42 TQFN package configuration. Ensure compliance with RoHS and Green manufacturing standards as specified in the datasheet. Cross-reference the part number against current product availability status to confirm active production status.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring DC-coupled video signal routing without external AC coupling capacitors. It is suitable for applications needing support for both DisplayPort 1.2 and HDMI 1.4 standards simultaneously. Consider its low skew characteristics for maintaining signal integrity in dense PCB layouts where minimal bit-to-bit skew is critical for high-speed data transmission.

Analog Switches - Special Purpose Part Context

This part belongs to the Pericom Semiconductor family of video switches, now under Diodes Incorporated. It is designed for high-performance multimedia applications requiring reliable signal switching between multiple video sources and displays. The ZHE suffix indicates the specific 42-pin Thin Quad Flatpack No-Lead package variant optimized for surface-mount assembly.

Analog Switches - Special Purpose Replacement Considerations

Consult the manufacturer's documentation for direct pin-compatible alternatives within the same series. Verify that any substitute maintains the required 4-lane mux/demux configuration and wide voltage range capabilities.
