MIPI CSI 2.0 Camera inputs
There are 3 independent CSI-2 x4 camera inputs available to the user using connectors P9, P11 and P12. These
are I-PEX Micro coax connectors that are compatible with Leopard Imaging camera’s LI-IMX185-MIPI-CS
(1080p), and LI-IMX274-MIPI-CS (4k). The RTG004 is setup to allow 3 2-lane cameras (IMX185) or 3 4-
lane cameras (IMX274). Up to 6 2-lane cameras can be supported with the VPG003, however, this RTM
design allows for only 3. Contact Connect Tech Sales if any different RTG interfaces are required.
USB 3.0/2.0 and OTG
The RTG004 has two ports capable of USB 3.0 or 2.0 (USB 3A and USB 3B with TX1 only, USB 3A with
TX2) and an extra USB 2.0 port used as either a host or client port selected through the USB ID pin state on J1
Header. Client mode is used to update the TX2/TX2i/TX1 module’s base software load. In host mode (with J5
jumper installed) the port acts as a standard host USB 2.0 port. The USB 3.0B port and the SATA port are
mutually exclusive and are selected via the J5 header block (Jumper installed for SATA).
Note: The USB3.0 B and SATA port selection jumper on the VPG003 (J2F) must match the settings of the
RTM.
Note: TX2 versions of the VPG003 only contain ONE USB 3.0 capable port.
SATA 2.0
One SATA Gen 2 port is available direct from the TX2/TX2i/TX1 for additional storage capability. The SATA
port and the USB 3B port are mutually exclusive and are selected via the J5 header block (installed for SATA
mode) on the RTG004.
Note: The USB3.0 B and SATA port selection jumper on the VPG003 (J2F) must match the settings of the
RTM.
General Purpose VPX Headers
The RTG004 contains access to some VPX specific backplane signals on the J1, J2 and J3 connectors. SM0-
SM1 are the I2C management interface for the backplane. GAx, are all the geographical addressing pins.
Other signals include SYS_RST#, SYS_CON#, and VBAT. An option to use the 3V3_AUX as opposed to the
RTC battery is available by installing the VBAT to 3V3_AUX jumper on J2.
