Audio Connector - 96Boards WinLink E850 Hardware User Manual

The WinLink E850 Development Board implementation supports two MIPI-CSI interfaces and therefore must support two I2C
interfaces. For MIPI-CSI0 the companion I2C2 is routed directly from the EXYNOS 850SoC. For MIPI-CSI1, the companion I2C
is I2C3.
SD/SPI
The 96Boards specification calls for an SD interface or a SPI port to be part of the High Speed Expansion Connector.
The WinLink E850 Development Board implements a full SPI master with 4 wires (96Boards SPI Configuration), CLK, CS, MOSI
and MISO. All the signals are connected directly to the Exynos 850 SoC.
These signals are driven at 1.8V.
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.
The WinLink E850 Development Board implements two CSI clocks which are connected directly to the Exynos 850 SoC. These
signals are driven at 1.8V.
USB
The 96Boards specification calls for a USB Data line interface to be present on the High Speed Expansion Connector.
The WinLink E850 Development Board implements this requirement by routing USB channel 3 from the USB HUB to the High
Speed Expansion Connector.
Reserved
The pin 60 of the High Speed Expansion Connector is pulled up to AVDD18_HSCON via R179 100K resistor.
