MIPI-CSI-2 Receiver
MIPI-CSI-2 devices are camera serial interface devices. They are categorized into two
types, a CSI transmitter device with Camera Control Interface (CCI) slave and CSI
receiver device with CCI master.
types, a CSI transmitter device with Camera Control Interface (CCI) slave and CSI
receiver device with CCI master.
Data transfer by means of MIPI-CSI is unidirectional that is, from transmitter to
receiver. CCI data transfer is bidirectional between the CCI slave and master.
receiver. CCI data transfer is bidirectional between the CCI slave and master.
Camera Serial Interface Bus (CSI) is a type of serial bus that enables transfer of data
between a Transmitter device and a receiver device. The CSI device has a point-to-
point connections with another CSI device by means of D-PHYs and as shown in
between a Transmitter device and a receiver device. The CSI device has a point-to-
point connections with another CSI device by means of D-PHYs and as shown in
.
Similarly, CCI (Camera Control Interface bus) is a type of serial bus that enables
transfer back and forth between the master CCI and a Slave CCI Unit.
transfer back and forth between the master CCI and a Slave CCI Unit.
D-PHY data lane signals are transferred point-to-point differentially using two signal
lines and a clock lane. There are two signaling modes, a high speed mode that operates
at 1000Mbs and a low power mode that works at 10Mbs. The mode is set to low power
mode and a stop state at start up/power up. Depending on the desired data transfer
type, the lanes switch between high and low power modes.
