PI2MEQX2505ZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI2MEQX2505ZHEX is a low-power MIPI D-PHY ReDriver compliant with the MIPI D-PHY 1.2 specification, designed for CSI-2 and DSI applications at data rates up to 2.5Gbps. It features four differential data lanes and one clock lane, providing programmable receiver equalization (3dB, 6dB, or 9dB), adjustable output swing (225mV to 275mV), and configurable pre-emphasis levels (0dB, 1dB, or 3dB). Operating on a 1.8V supply (1.62V to 1.98V), it supports ULPS and LP power states with sub-mW shutdown consumption. The device utilizes a 28-contact TQFN package measuring 5.5 x 3.5 mm and operates within an industrial temperature range of -40°C to +85°C.

• Clamshell mobile devices
• Tablet computer displays
• Camera sensor interfaces

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the part number suffix ZHEX corresponds to the Tape and Reel packaging format as specified in the ordering information. Confirm that the design requirements align with the industrial temperature range (-40°C to +85°C) rather than automotive specifications, which require the PI2MEQX2505Q variant. Ensure compliance with RoHS 3 and halogen-free standards if required by the target market regulations.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal regeneration over PCB traces, connectors, or cables for MIPI D-PHY 1.2 interfaces. It is suitable for extending signal paths between CSI-2 sources and sinks where inter-symbol interference compensation is necessary. Consider the available pin-adjustable configurations for equalization and swing if I2C control is not utilized in the final system architecture.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to Diodes Incorporated's ReDriver product line, specifically engineered for mobile and computing applications. It serves as a signal integrity solution for high-speed MIPI interfaces, addressing attenuation issues in modern high-resolution camera and display link designs. The ZHEX suffix indicates the specific tape-and-reel packaging configuration for automated assembly processes.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The datasheet explicitly identifies the PI2MEQX2505A as the recommended replacement for new designs. While functionally similar, the A-series variant may offer updated manufacturing controls or availability status compared to the Not Recommended for New Design designation of the base model.
