PI3WVR12412ZHE+DRX

Analog Switches - Special Purpose Overview

The PI3WVR12412 is a multi-standard video switch supporting DisplayPort 1.2 and HDMI 1.4. It features a 4-lane, 1:2 mux/demux for high-speed lanes and a dedicated 1-channel 1:2 mux/demux for HPD signals. The device passes differential signals up to 1.2 V peak-to-peak with a common-mode voltage from 0 to 3.4V, enabling DC-coupled operation. Key electrical parameters include -1.6 dB insertion loss at 2.7 GHz, a -3 dB bandwidth of 4.6 GHz, and return loss of -16 dB at 2.7 GHz. Crosstalk is -28 dB at 5.4 Gbps, with channel-to-channel skew of 35 ps max and bit-to-bit skew of 5 ps typical. It operates on a 3.3V +/-10% supply and offers 2kV HBM ESD tolerance.

Analog Switches - Special Purpose Feature Summary

• Supports RBR, HBR1, and HBR2 data rates across four high-speed lanes
• Enables DC-coupled multi-standard operation by eliminating AC coupling capacitors
• Integrates switching for DP AUX and HPD sideband signals
• Provides low signal attenuation and minimal skew for dense PCB designs

Analog Switches - Special Purpose Applications

• Routing DisplayPort and HDMI signals between source and sink
• Video switching in consumer electronics and displays
• High-density PCB designs requiring space-saving DC-coupling

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details such as tape and reel quantities or lead-free status. Ensure the component meets required environmental standards for the intended application. Cross-reference the full part number with official distributor catalogs to confirm availability and correct pinout configuration before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring support for DisplayPort 1.2 and HDMI 1.4 standards with DC-coupled interfaces. Consider its wide voltage range capability for applications needing flexible power supply integration. Evaluate the low skew and crosstalk specifications for high-integrity signal routing requirements in compact form factors.

Analog Switches - Special Purpose Part Context

This device belongs to the Pericom (Diodes Incorporated) video switch family, designed for high-speed multimedia signal routing. It addresses the need for multi-standard compatibility in modern display interfaces. The PI3WVR12412 specifically targets applications where board space optimization and signal integrity are critical constraints.

Analog Switches - Special Purpose Replacement Considerations

Check for direct substitutes within the PI3WVR series that may offer different lane counts or standard support. Verify pin compatibility and electrical parameter equivalence if considering alternative vendors. Ensure any replacement maintains the required DC-coupling capabilities and signal speed ratings.
