The device complies with MIPI D-PHY1.2 standard and can be used in either a MIPI CSI-2 or MIPI DSI application at datarates of up to 2.5Gbps in D-PHY. The device compensates for PCB, connector, and cable related loss and switching related loss to provide the optimum electrical performance from a CSI2/DSI source to sink. The inputs of PI2MEQX2503’s feature configurable equalizers. The PI2MEQX2503 output voltage swing and edge rate can be adjusted by changing the pin state. It is optimized for mobile applications, and contains activity detection circuitry on the D-PHY Link interface that can transit into a lower power mode when in ULPS and LP states. The PI2MEQX2503 supports industrial temperature range from -40°C to 85°C. Application(s) • Notebook PC • Clamshell • Tablets • Camera 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.

A Product Line of Diodes Incorporated PI2MEQX2503 Detailed Description Overview The PI2MEQX2503 is a one to two lane and clock MIPI D-PHY re-driver that regenerates the D-PHY signaling. The device complies with MIPI D-PHY1.2 standard and can be used in either a MIPI CSI-2 or MIPI DSI application at datarates of up to 2.5Gbps in D-PHY. The device compensates for PCB, connector, and cable related frequency loss and switching related loss to provide the optimum electrical performance from a CSI2/DSI source to sink. The PI2MEQX2503 D-PHY inputs feature configurable equalizers. The PI2MEQX2503 output...

Feature Description HS Receive Equalization The PI2MEQX2503 supports three levels of receive equalization to compensate for ISI loss in the channel. These three levels are 3dB, 6dB, and 9dB at 1250Mhz. The equalization level used by the PI2MEQX2503 is determined by the state of the EQ/SCL pin at the rising edge of RSTN. If necessary, the receiver equalization level can also be set through writing to the RXEQ register via the local I2C interface. Table 1.
