CSI Camera Connector
SBC-C20 with NXP iMX8M Processor includes an Image Processing Subsystem, that can be used for video applications, like video-preview,
video recording and frame grabbing.
It is possible to access to the video input port through an FFC/FPC connector, type HIROSE p/n FH12-18S-0.5SH(55) which is able to
accept 18 poles 0.5mm pitch FFC cables.
The pinout of this connector is shown in the table on the left. All CSI differential pairs are managed
CSI_P1_DP0 / CSI_P1_DN0: CSI2 Camera serial input, Receiving Input Differential pair #0.
CSI_P1_DP1 / CSI_P1_DN1: CSI2 Camera serial input, Receiving Input Differential pair #1.
CSI_P1_DP2 / CSI_P1_DN2: CSI2 Camera serial input, Receiving Input Differential pair #2.
CSI_P1_DP3 / CSI_P1_DN3: CSI2 Camera serial input, Receiving Input Differential pair #3.
CSI_P1_CKP / CSI_P1_CKN: CSI Camera, Clock input differential pair.
MIPI_CSI0_EN: External camera module Power enable signal. It is an active high signal with electrical
level VDD_3P3V.
MIPI_CSI0_MCKL_OUT: Master Clock, it is managed by i.MX8M GPIO_15 pin. It is suggested,
however, to use camera modules with onboard crystal / oscillator, and avoid using this signal.
Indeed, it could cause problems for EMI compliance requirements.
MIPI_CSI0_I2C0_SCL: general purpose I2C Bus clock line. Output signal, electrical level VDD_3P3V with a 2k2
-up resistor. It is managed by i.MX8M processor s
I2C controller #2.
MIPI_CSI0_I2C0_SDA: general purpose I2C Bus data line. Bidirectional signal, electrical level VDD_3P3V with a 2k2
-up resistor. It is managed by i.MX8M
processor s I2C controller #2.
MIPI_CSI0_RST_B: External camera module reset signal output, it is an active low signal.
