PI3DPX1202A1ZBEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1202A1ZBEX is a DisplayPort 1.2 compliant, low-power Redriver manufactured by Diodes Incorporated. It operates on a single 3.3V power supply and supports data rates of 1.62, 2.7, and 5.4 Gbps with DDC/Aux signal switching. The device features four differential input/output lanes and utilizes an internal Aux listener to automatically configure output swing and pre-emphasis based on link training values. It includes pseudo-adaptive equalization, hot plug detect, and cable detection functions. The component is housed in a 48-pin TQFN package measuring 7x7mm.

• Supports DP 1.2 specification with automatic link training configuration via built-in Aux listener
• Features ultra-low power design with individual lane power down when no signal is present
• Includes dual mode DisplayPort Input/Output with TMDS clock frequencies up to 340 MHz
• Provides pin control for EQ, Output Voltage Swing, and Pre-Emphasis settings

Signal Buffers, Repeaters, Splitters Applications

• Notebook PCs
• All-In-One (AIO) and Desktop PCs
• Graphic Cards

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'I' for industrial temperature range requirements. Confirm that the 'E' suffix indicates Pb-free and Green compliance. Ensure the 'X' suffix matches the required Tape/Reel packaging format. Cross-reference the datasheet revision history for any updates to electrical characteristics or timing parameters before finalizing procurement specifications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for designs requiring a limiting-type Redriver compliant with DP 1.2 standards. It serves as a drop-in replacement for the PI3EQXDP1201. Consider its lower power consumption compared to previous generations. Verify compatibility with the system's I2C address configuration and ensure sufficient thermal relief for the exposed pad in the TQFN package.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3DPX1202A product line from Diodes Incorporated. It is functionally similar to the PI3DPX1202A2 but lacks the dedicated AUTO_EQ pin found in the A2 variant. The A1 version relies on internal pull-ups for certain control pins. It is distinct from the linear-type PI3EQXDP1201 and the newer DP 1.4 compliant PI3DPX1203B.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI3EQXDP1201 is documented as a pin-to-pin replacement option. Designers should verify that the fixed EQ capabilities of the PI3EQXDP1201 meet the system's latency and performance requirements. Other family members like the PI3DPX1202A2 offer enhanced auto-EQ pin control.
