Interfaces
Camera connector
Camera connector is configured with one-to-one matching interfaces and pinout as a Simera Sense xScape imagers. It contains I2C, SPI, PPS, LVDS pairs compatible with Simera protocol as well as LVDS pairs for SpaceWire signals, and 5V power output to the camera.
CameraLink
In addition to the Camera conncetor, SKAIDOCK features second interface that provides 21 LVDS pairs to support connection of imaging systems utilizing CameraLink protocol or high-speed communication subsystems.
CAN
SKAIDOCK features two CAN interfaces, connected to the PS side of the MPSoC. Bus termination can be enabled in the connector, by connecting specified pins.
Serial
Serial RSxxx interface is dependent on Q8 configuration (1x RS422 or 1x RS485 or 2x RS232).
Ethernet
SKAIDOCK incorporates 2 Ethernet interfaces operating at 1Gbps
SPI
SPI interface also operates at 3V3 and has also two different connectors. SPI in the Camera connector has one chip select pin, standalone SPI has three chip select pins. Only one connector can be used.
Qualification
SKAIDOCK has been qualified for operation in a space environment. During thermal-vacuum (TVAC) testing, it was tested for operational temperatures between -40°C and +60°C.
The board has also undergone sine and random vibration testing, shock testing, and radiated emissions measurements. The Xiphos Q8 module, with extensive flight heritage, has also been fully qualified.
