Low-power redriver supports MIPI D-PHY 1.2 protocols

22-11-2023 | Diodes Inc | Semiconductors

Diodes Incorporated has released a low-power, high-performance MIPI D-PHY 1.2-compliant signal ReDriver. The PI2MEQX2503 regenerates signals transmitted at data rates to 2.5Gbps from cameras to displays in different applications, including laptops, tablets, mobile phones, IoT devices, commercial displays, augmented reality headsets, drones, and robots.

Supplying a dual-data-lane equaliser and a single clock lane, the device compensates for PCB, connector, cable, and switching-related losses. This ReDriver facilitates 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 device is more power efficient than a ReTimer. Also, its low-power (5mW), ultra-low-power (2mW), and shutdown (0.2mW) modes of operation provide further power savings, helping to prolong battery life. Other features like programmable receiver equalisation, output swing, and pre-emphasis compensate for channel loss with low latency over longer-length traces whilst minimising power consumption.

The device supports a -40C to +85C operating temperature range for industrial applications for added robustness. This space-saving ReDriver is supplied in a very small X1QFN-24 (XEA24) package measuring just

2mm x 4mm.
