115-083584-00 Main Board Assembly
(FRU)
Function description:
The main board is divided into the front end and back end.
The front end of the main board provides the following functions:
1. Transmission: The front-end FPGA controls 128 channels to transmit high-voltage ultrasonic
signals to the probe, so as to realize transmission focusing of the machine.
2. Reception: The front-end FPGA controls 128 channels to receive ultrasonic echo signals from
the probe, so as to realize reception focusing of the machine.
3. ATGC module
4. Support for data caching through the IQ (frame buffer), UP (upload), SCAN (scan), AD
(analogue-to-digital conversion) channels.
5. Generation and delivery of front-end clocks.
6. Imaging-related logic functions, which are carried by the front-end FPGA.
7. Execution of front-end module reset, online upgrade, and module information management.
8. Probe-related control and management.
9. Communication and control for image scanning-related accessories.
10.Distributed acoustic power testing signals: Acoustic power testing is output from FPGA to the
socket in the main board.
11.Integrated PHV output module.
The back end of the main board provides the following functions:
1. Support for the COME module of the Type 6 port.
2. Support for the GPU module of the 3.1 Type A port.
3. Support for 23.8-inch touch screen, with the resolution of 1920 x 1080.
4. Support for wired networks and wireless networks (M.2 port).
5. Support for SSD, with 256 GB or more storage (M.2 port).
6. Support for four USB 3.0 ports.
7. Support for the USB 3.0 Type C port.
8. Support for the output port of the HDMI replication main display, with the default resolution of
1920 x 1080, and support for adaptive output of the 1280 x 1024, 1280 x 720, and 1024 x 768
resolutions. Display of the full screen and standard area for the main display.
9. Support for the 4G module.
10.Support for automatic control of the ambient light brightness for the display.
11.Support for secondary screen display and information such as the battery capacity upon
power-off.
12.Support for speaker output for the machine, with the left and right channel output of 4 ohm/2
W.
13.Support for the ultrasonic Doppler software to process echo data.
