PI3HDMI1310-AZLEX

Specialized Overview

The PI3HDMI1310-AZLEX is a 3-to-1 HDMI Mux/Demux switch manufactured by Diodes Incorporated. It operates on a 72-contact TQFN package and supports data rates up to 3.4Gbps with 16-bit color depth per channel. The device utilizes a 3.3V power supply and accepts 5V standby power from the VDD50 pin. Key electrical parameters include a typical operating current of 10mA, a standby current of 5mA, and a -3dB bandwidth of 3.0GHz for TMDS channels. It provides low bit-to-bit skew of 15ps and channel-to-channel skew of 35ps.

Specialized Feature Summary

• Features differential channel multiplexing for TDMS signals and DDC signals.
• Includes non-EQ blocking circuitry to utilize ideal equalization found in main receiver chipsets.
• Supports Energy Star compliance through low power consumption design.
• Provides ESD protection on all I/O pins meeting ±8kV contact and 7kV HBM standards.

Specialized Applications

• High-resolution video networks based on DVI/HDMI standards
• Next generation HDTV systems
• PC graphics interfaces

Specialized Procurement Notes

Verify the ordering code suffix ZL indicates Pb-free and Green packaging within the 72-contact TQFN format. Confirm that the specific part number includes the required tape and reel designation if automated assembly is intended. Ensure the component meets RoHS3 and REACH regulatory requirements as specified in the manufacturer documentation.

Specialized Selection Notes

Select this component for designs requiring a 3:1 HDMI switch with minimal signal degradation. The device supports both source and sink configurations for high-speed video and DDC ports. Verify that the system can accommodate the 3.3V logic levels and the external pull-up requirements for HPD open-drain outputs.

Specialized Part Context

This IC belongs to the Pericom PI3HDMI series of switch circuits designed for high-resolution video networks. It is engineered specifically to meet ATC-Sink requirements for Hot Plug Detect (HPD) ports. The architecture ensures high channel-to-channel noise isolation and low bit-to-bit skew for reliable signal transmission.

Specialized Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.

Specialized FAQ

How is the output port selected?

Port selection is controlled by two pins, SEL1 and SEL2. Setting SEL1=0 and SEL2=0 selects Port A, 0 and 1 selects Port B, and 1 and 0 selects Port C. Setting both to 1 places the outputs in a Hi-Z state.

What is the function of the HPD_Sink pin?

The HPD_Sink pin is an input used to drive each HPD channel. It requires an external pull-down transistor circuit before connecting to the HDMI/DVI connector to manage the Hot Plug Detect status.

Does the device support DDC communication?

Yes, it includes a passive NMOS-based 3:1 mux for DDC channels (DDC_CLK and DDC_Data). This section remains active even when the 3.3V supply is removed, provided the 5.0V from the TMDS connector is connected.
