PI3DPX1203BZHE

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1203BZHE is a DisplayPort 1.4 compliant, four-channel linear redriver manufactured by Diodes Incorporated. It supports data rates up to 8.1 Gbps (HBR3) and operates on a single 3.3V power supply with a typical operating current of 243 mA. The device features latency-free signal transmission and transparent link training support. Configuration is achieved via pin-strapping or an I2C interface, allowing independent control of equalization, voltage swing, and flat gain for each channel.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific package code ZHE corresponds to the required 42-pin TQFN form factor. Confirm that the ordering suffix indicates standard commercial temperature range unless industrial grade is explicitly required. Ensure the procurement documentation matches the manufacturer's datasheet DS39880 Rev 1-2 for accurate electrical parameters.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring high-speed DisplayPort signal integrity over lossy channels. The linear architecture allows for flexible board layout compared to limiting amplifiers. Verify that the system design accommodates the 3.3V supply requirement and provides adequate thermal dissipation for the exposed pad ground connection.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3DPX1203B product line from Diodes Incorporated. It serves as a direct replacement for previous generations like the PI3DPX1203, offering improved power consumption characteristics while maintaining pin-out compatibility. The ZHE suffix specifically denotes the 42-pin TQFN package variant within this family.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI3DPX1203B is designed as a drop-in compatible replacement for the legacy PI3DPX1203 model. Designers should verify that the existing PCB footprint aligns with the 42-pin TQFN dimensions specified in the mechanical outline section of the datasheet.
