Mini-HDMI Connector
(J25)
The mini-HDMI connector is used as HDMI output of MCIMX53SMD board. The power source for the HDMI
Bridge SiI9022 is DCDC_3V3_BB, and the power source for mini-HDMI connector is DCDC_5V_BB.
3.6.
SD Card Slot (J13)
The SD Card slot is a 5-in-1 SD/MMC connector that acts as memory media slot. The power source for the SD
Card Slot is the auxiliary DCDC buck (DCDC_3V3_BB). The SD Card slot can be configured as the boot source
with an alternate boot option setting. It can also be configured for either SD or MMC card operation (see the
Boot Mode Operations and Selections
section). The SD Card Slot supports full 4-bit parallel data transfers and
can support SDIO cards (such as, WiFi and BT) designed to fit in a standard SD card slot.
3.7.
SATA Connector (J5)
The SATA connector provides a means to connect an external SSD SATA drive to the MCIMX53SMD board.
Power for the SATA drive needs to be supplied by SATA_5V and SATA_3V3. The developer can use boot
configure to boot the SATA drive.
3.8.
VGA Dock (J131)
A Dock with VGA signal is on the MCIMX53SMD board. VGA is the output that comes directly from the i.MX53
processor with minimum external components required. Power for the TVE module of the i.MX53 processor is
supplied by VLDO7 of the PMIC and is set to 2.75V. If VGA output is not desired, the PMIC can be programmed
to turn off VLDO7 to conserve power. The VGA output supports a variety of video formats up to 150
Megapixels per second. Level shifters are required on the Horizontal and Vertical Synchronization signals as
well as the VGA I2C communications signals in order to meet VGA specifications. Meanwhile, Audio LINEIN and
LINEOUT are supported on the Dock. The Audio LINEIN and LINEOUT are from SGTL5000 on MCIMX53SMD
board. Another feature on Dock is USB.
3.9.
LVDS Video Output (J28, J29)
The LVDS module of the i.MX53 processor is connected to two 30-pin LVDS connectors. Both connectors are
pinned out on the MCIMX53SMD board, though the i.MX53 processor is capable of outputting to two separate
LVDS displays. The pin outs on the LVDS connector match the optional cable and 10” HannStar LVDS display
