Diodes Incorporated has announced the release of the PI2MEQX2505Q, an automotive-compliant 2.5Gbps MIPI D-PHY ReDriver designed to improve signal integrity in automotive camera monitoring systems and advanced driver assistance systems (ADAS). The new device targets the growing need for reliable, high-speed data transmission as vehicle architectures incorporate more cameras and higher-resolution imaging sensors.
The PI2MEQX2505Q operates at 1.8V and supports the MIPI D-PHY 1.2 protocol, offering four differential data lanes and one clock lane. It is designed to regenerate D-PHY signals across channels that include printed circuit board traces, connectors, and cables, compensating for frequency loss and maintaining signal quality between CSI-2 or DSI sources and sinks.
With support for data rates of up to 2.5Gbps, the ReDriver is positioned to meet the increasing bandwidth demands of modern automotive camera systems. This capability enables support for higher pixel counts and more complex imaging workloads commonly required in surround-view, driver monitoring, and ADAS applications, differentiating the device from conventional retimer solutions with lower throughput.
The device includes a range of programmable features aimed at system optimization and design flexibility. These include configurable receiver equalization, adjustable output voltage swing, and selectable transceiver pre-emphasis levels. Engineers can set receiver equalization to 3dB, 6dB, or 9dB at 1250MHz, choose pre-emphasis levels of 0dB, 1dB, or 3dB, and adjust output voltage swing up to 275mV. Configuration can be managed through a local I2C interface or via pin-strap controls, allowing adaptation to different board layouts and channel conditions.
Power efficiency is a key focus, particularly for battery electric vehicles. The PI2MEQX2505Q supports ultra-low power and low-power states, with integrated activity-detection circuitry enabling automatic transitions when the D-PHY link is idle. According to Diodes, the device consumes up to 200mW in active mode, approximately 6mW in low-power mode, and a maximum of 0.2mW in standby.
Housed in a compact 3.5mm × 5.5mm W-QFN package, the ReDriver is designed for space-constrained automotive electronics. The PI2MEQX2505Q is priced at $0.88 in 3,500-piece quantities, with additional industrial and commercial variants also available.
