Diodes Incorporated, a leading global manufacturer and supplier of semiconductor devices, has recently released a low-power, high-performance MIPI D-PHY 1.2-compliant signal ReDriver. The PI2MEQX2503 regenerates signals transmitted at data rates up to 2.5Gbps from cameras to displays in various applications, including laptops, tablets, mobile phones, Internet-of-Things (IoT) devices, commercial displays, augmented reality headsets, drones, and robots.

Featuring a dual-data-lane equalizer and a single clock lane, the PI2MEQX2503 compensates for PCB, connector, cable, and switching-related losses. This ReDriver enables optimum electrical performance from a CSI2 source to a DSI sink. It operates at up to 2.5Gbps to comply with the MIPI D-PHY 1.2 specification for camera images with increasing numbers of pixels.

The 120mW active-mode power consumption of the PI2MEQX2503 is more power efficient compared to a ReTimer. In addition, its low-power (5mW), ultra-low-power (2mW), and shutdown (0.2mW) modes of operation offer further power savings, helping to extend battery life. Other features like programmable receiver equalization, output swing, and pre-emphasis compensate for channel loss with low latency over longer-length traces while minimizing power consumption.

For added robustness, the PI2MEQX2503 supports a -40°C to +85°C operating temperature range for industrial applications. This space-saving ReDriver is provided in a very small X1QFN-24 (XEA24) package measuring only 2mm x 4mm.
