Low-power redriver improves signal integrity of high-speed MIPI data paths

Diodes Incorporated has announced the latest addition to its broad portfolio of ReDrivers™ products with the release of a 1.8 V, 2.5 Gbits/s redriver which has four data lanes. The DIODES™ PI2MEQX2505 redriver is the industry’s first to support the MIPI D-PHY 1.2 protocol. The PI2MEQX2505 enables board designers to extend trace lengths without compromising latency or power consumption.

The PI2MEQX2505 may be used to extend PCB trace lengths in camera systems with a MIPI D-PHY interface while minimizing both latency and power consumption. The redriver consumes 135 mW in active mode, 5 mW in low-power mode, 2 mW in ultra-low power mode, and just 0.2 mW in standby mode. This low power consumption helps to extend the battery life of portable devices that include MIPI cameras, such as laptops and personal computers.

This redriver product has four differential channels providing programmable receiver equalization, output swing, and pre-emphasis functions. Equalization is controlled by either I2C interface or pin-strap control. It optimizes performance over a variety of physical media by reducing inter-symbol interference. 

The PI2MEQX2505 is supplied in a 28-lead TQFN package which measures 3.5 mm x 5.5 mm, enabling designers to implement systems with high-density channel routing.
