HiKey960 Development Board Hardware User Manual
10/20
The Hikey960 Development Board deploys the built-in DSI interface as the source for the HDMI output.
A peripheral Bridge IC (U1901, ADV7535) performs this task and it supports 1080p at 30Hz.
MIPI-DSI
The 96Boards specification calls for a MIPI-DSI implementation via the High Speed Expansion
Connector.
The Hikey960 Development Board implements a 4-lane MIPIDSI interface meeting this requirement. It
can support up to 2560*1600@60fps. The Hikey960 Development Board routes the MIPIDSI interface
signals to the DSI-0 interface of the Kirin960.
Camera Interface
The 96Boards specification calls for two camera interfaces.
The Hikey960 Development Board supports two camera interfaces, one with a 4-lane MIPICSI interface
and one with 2-lane MIPICSI interface, meeting this requirement. The 4-lane MIPICSI interface can
support 26M camera and the 2-lane MIPICSI can support 8M camera.
USB Ports
The Hikey960 Development Board supports a USB OTG port and three USB host ports via a USB MUX.
The input channel( D+/D-) of USB MUX is connected to the usb port of the SOC, and the two output
channels(1D+/1D-,2D+/2D-) are connected to type C USB port and USB hub respectively. The three
USB host ports are connected to the downstream ports of the USB hub. The control of MUX is done via
a software controlled GPIO. When this signal is logic low, ‘0’, the USB data lines are routed to the type
C USB connector. When ‘USB
SW
SEL’ is logic level high, ‘1’, the USB data lines are routed to USB
HUB.
USB Host ports
The Hikey960 Development Board supports three USB host port via a USB hub (U1803 USB5734). Its
upstream signal is connected to USB interface of Kirin960.
Port 1 of the USB HUB is routed to J1702, a Type ‘A’ USB Host connector. A current
controller (U1704) sets the Power Current limit to 1A.
Port 2 of the USB HUB is routed to J1801, a Type ‘A’ USB Host connector. A current limited
controller (U1806) sets the Power Current limit to 1A.
Port 3 of the USB HUB is routed to the High Speed Expansion connector. No current limited
controller is implemented on the board for this channel.
