PI3DPX1203ZHE

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1203ZHE is a DisplayPort 1.3 compliant linear redriver designed for source, active cable, and sink-side applications. It supports an 8 Gbps link speed with a single differential channel configuration. The device operates on a 3.3V supply voltage and is housed in a 42-pin TQFN package measuring 3.5mm x 9mm. Key electrical features include programmable input equalization, output swing, and flat gain control to optimize signal integrity. It supports pin strap or I2C programmability for device configuration settings.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports flexible placement for active cables, sinks, and sources while maintaining transparent DisplayPort link training without requiring auxiliary link training listener circuits.
• Features independent channel configuration of input equalization, output swing, and flat gain to reduce intersymbol interference and increase link margin for systems implementing decision feedback equalizers.
• Allows direct connection of the auxiliary channel from source to sink device and includes a low-level input signal detection and output squelch function.

Signal Buffers, Repeaters, Splitters Applications

• PCs and Peripherals
• DisplayPort Active Cables

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets the required environmental standards and RoHS compliance levels before procurement. Cross-reference the datasheet revision date to guarantee access to the most current electrical characteristics and mechanical drawings.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for DisplayPort 1.3 applications requiring an 8 Gbps data rate. It is suitable for designs needing transparent link training and low latency. Consider the 42-pin TQFN footprint for space-constrained layouts. Verify that the 3.3V supply voltage aligns with the system power architecture and that I2C or pin-strap configuration methods fit the design constraints.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3DPX1203 family of linear redrivers manufactured by Diodes Incorporated (formerly Pericom). It is specifically engineered to extend the reach of DisplayPort signals by compensating for channel loss. The device integrates linear equalization to improve signal quality across various physical mediums used in modern display interfaces.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Check for compatible parts within the same product family that may offer different package options or updated feature sets. Ensure any substitute maintains the 8 Gbps data rate and 3.3V operating voltage. Verify pin compatibility if replacing directly on a PCB layout.
