2.6.8
Parallel Camera Interface
i.MX6 SODIMM SOM supports one 8bit/12bit camera interface on SODIMM Edge Connector. i.MX6
CPU’s CSI parallel
port is used for camera interface which provides direct connectivity to most relevant CMOS sensors and CCIR656
video interface. The sensor is the master of the pixel clock (PIXCLK) & synchronization signals where synchronization
signals can be received using dedicated control signals method (HSYNC & VSYNC) or controls embedded in data
stream method (CCIR.656 protocol).
For more details, refer SODIMM Edge connector pins 38, 75, 93, 96, 100, 101, 104, 119,120, 121, 123 & 126 for 8bit
camera interface on
For 12bit camera, please refer pins 63, 66, 70 & 110 for extra 4bits on
Note: If Parallel camera interface is used on SODIMM edge, then UART4 & UART5 cannot be used with hardware flow
control for request to send and clear to send signals.
Note: If Parallel camera is used with 12bit interface on SODIMM edge, then eCSPI2 interface cannot be used.
2.6.9
Parallel RGB Display Interface
i.MX6
SODIMM SOM supports one 24bpp Parallel RGB display interface on SODIMM Edge connector. i.MX6 CPU’s
IPU is used for parallel LCD display interface which supports upto 24bit data bus (8bits/colour). i.MX6
CPU’s LCD can
support data rate up to up to 225 Mpixels/sec (for example, WUXGA at 60 Hz or dual HD1080 and WXGA at 60 Hz).
For more details, refer SODIMM Edge Connector pins 143, 144, 145, 146, 148, 149, 150, 152, 153, 154, 155, 156, 157,
158, 159, 161, 162, 163, 164, 165, 166, 167, 168, 170, 171, 172, 173, 174 on
Note: i.MX6 Duallite and i.MX6 Solo CPU supports only one IPU and so at any time only two display interfaces
(including LVDS, HDMI & Parallel RGB) can be supported.
2.6.10
LVDS Interface
i.MX6 SODIMM SOM supports one LVDS display port on SODIMM Edge connector. i.MX6
CPU’s IPU with LDB is used
for LVDS interface. The purpose of the LDB is to support flow of synchronous RGB data from the IPU to external
display devices through the LVDS interface. It consists of one clock pair & four data pairs and can support data rate
up to 170Mhz (WUXGA 1920x1200). i.MX6 CPU LVDS interface supports 18bit RGB and 24bit RGB colour mapping.
i.MX6 CPU LVDS0 is directly connected to SODIMM Edge connector. LVDS backlight enable and LVDS backlight
brightness control (PWM) are supported on SODIMM Edge connector from i.MX6 CPU pins NANDF_ALE and GPIO_9.
For more details, refer SODIMM Edge connector pins 47, 48, 50, 52, 53, 54, 55, 56, 57, 58, 59 & 138 on
Note: i.MX6 Duallite and i.MX6 Solo CPU supports only one IPU and so at any time only two display interfaces
(including LVDS, HDMI & Parallel RGB) can be supported.
