Speed Expansion Connector.
The RB5 provides a full SD master with SDIO (CLK/CMD/D0~D3) from QRB5165 SoC. All
signals are driven at 1.8V and 1.8V only.
5.1.7 Camera Clocks
The 96Boards specification calls for one or two programmable clock interfaces to be
provided on the High Speed Expansion Connector. These clocks may have a secondary
function of being CSI0_MCLK and CSI1_MCLK. If these clocks can't be supported by the
SoC than an alternative GPIO or No-Connect is allowed by the specifications.
HS1 in RB5 implements two CSI clocks, CLK0/CSI0_MCLK, GPIO_94 for CSI0 and
CLK3/CSI3_MCLK, GPIO_97 for CSI3. These signals are driven at 1.8V.
5.1.8 USB
The 96Boards specification calls for a USB data line interface to be present on the high-
speed expansion connector.
RB5 implements this requirement. In HS1, USB HS DP/DM signals are routing from a USB
HUB.
