Process Flowchart

  1. Write data of the register of the DS90UB971.
  1. The DS90UB971 is the master of the I2C bus.
  1. The DS90UB971 generates signals to let AR0820 send its image data.
  1. The DS90UB971 sends the image data out through the coaxial cable after it receives the data.
  1. The calibration data is written to the EEPROM.

Serializer & Master of I2C
DS90UB953-Q1
The DS90UB953-Q1 serializer is part of TI's FPD-Link III device family designed to support high-speed raw data sensors including 2.3MP imagers at 60-fps and as well as 4MP, 30-fps cameras, satellite RADAR, LIDAR, and Time-of-Flight (ToF) sensors. The chip delivers a 4.16-Gbps forward channel and an ultra-low latency, 50-Mbps bidirectional control channel and supports power over a single coax (PoC) or STP cable.

DESCRIPTION
I2C_SDA
I/O, OD
I2C Data snd Clock Pins for the bidirectional control bus communication. Typically pulled up by 2.2-kΩ to 4.7-kΩ resistors to either 1.8-V or 3.3-V supply rail depending on IDX setting.
I2C_SCL
I/O, OD
I2C Data snd Clock Pins for the bidirectional control bus communication. Typically pulled up by 2.2-kΩ to 4.7-kΩ resistors to either 1.8-V or 3.3-V supply rail depending on IDX setting.
