The 3V3STB takes EDC_POWER from the adapter or the BATTERY_BUS from the batteries as the input and generates 3V3STB via linear voltage-stabilizing chip TPS715A01.
TPS715A01 is equipped with current-limiting function itself. The Maintenance Points of 3V3STB Circuit
If the 3V3STB unit is faulty, first check whether the input voltage of U12 PIN1 is normal; if it is normal, it indicates that the U12 is damaged or the fault is caused by the over-current or short circuit of the load.

protection.
The Maintenance Points of 5VSTB_CPU Circuit
If the 5VSTB_CPU unit is faulty, first check whether the input voltage of U35 PIN2 is normal and whether the enabling signal of PIN4 is 3.3V; if they are all normal, it indicates that the U35 is damaged or the fault is caused by the over-current or short circuit of the load; if PIN4 is low level, check whether the system main board provides 5VSTB_EN# signal and whether the feedback connection or overvoltage circuit is normal.

4.2.1.6 PHV Circuit Unit
Basic Principle of PHV
The PHV circuit consists of PHV1P, PHV1N, HV2P and PHV2N, of which, the PHV1P and PHV1N consist of PW and CW output. The PW output range of PHV1 is ±13V~±85V, and the CW output range is ±2V~±4V. Only PW output of PHV2 is available, and the output range is ±5V~±85V.
The input of the PW circuit of the 4 PHVs is controlled +12V, which is under the control of PMOS Q5.The PW output voltage of PHV1P and PHV2P is generated by BOOST circuit. The controlling IC is TL594, which is frequently adopted by our company. The range of output voltage of PHV2P is +5V~+85V, so when the output voltage is over than 15V, the input is +12V; and when the output voltage is lower than 15V, the input is +5V. Both the two inputs are under the control of output voltage controlling signal. The PW output voltage of PHV1N and PHV2N is generated by BUCK-BOOST circuit. The controlling IC is MAX1847, which is frequently adopted by our company.
The CW output of PHV1P and PHV1N is generated through linear voltage-stabilizing. The input of CW circuit of PHV1P is +5V and the chip LT1963 LDO is adopted for the linear voltage-stabilizing; the input of CW circuit of PHV1N is -5V, and the chip LT1185 LDO is adopted for the linear voltage-stabilizing. The voltage of CW output is regulated by the output voltage controlling signal. When the controlling signal is 0.45~2.25V, the corresponding output voltage is ±2V~±4V.
The 4 PHV are all equipped with overvoltage protection, and the overvoltage protection of each circuit is independent. The overvoltage will not be locked, and the voltage is about 93V when overvoltage occurs.
The 4 PHV are all equipped with over-current protection. In PW mode, once over-current occurs, all the 4 PHV PW outputs and ±95V will be switched off, while the CW output is not influenced. The over current protection in CW mode is implemented by current-limiting of LDO chip itself. Only the output is cut off and other outputs are not influenced.

4.2.1.10 -5V and -12V Circuit Unit
Basic Principle of -5V and -12V
The implementations of -5V and -12V are the same. The negative voltage IC MAX1847 is adopted for both circuits. The -5V and -12V are both equipped with overvoltage and over-current protection circuits, so once either overvoltage or over-current occurs, both circuits will be cut off and locked.

4.2.1.11 Charging Unit
Basic Principle of Charging Unit
The rise-and-fall charging chip MAX1870A made by MAXIM is adopted for both charging units A and B.
The MAX1870A enabling is controlled by the system’s main board and batteries’ temperature, and eventually controlled by level of PIN15. When PIN15 is high level (about 5V), the charging is enabled; when PIN15 is low level, the charging is disenabled. The charging current is affected by the status of the batteries and the load current of the main unit. The charging circuit regulates the charging current dynamically according to the load current of the main unit to ensure fast charging and the load current of the adapter is not overloaded when the system is on.

The basic structure of the front-end circuit is shown in figure below:
Fig 4-8 Diagram of Front-end Circuit
The receiving circuit of the main board consists of channel switching and receiving circuits.
Channel switching circuit
Transmitting and receiving circuits are 64 channels, but the actual transducer is 128 channels, so channel switching circuit is needed to switch the 64 channels of the transmitting and receiving into 128 channels. 8 channel conversion circuit is completed through 16-channel high voltage switch chip. Refer to the principle diagram for the principle.
Receiving circuit
The receiving circuit consists of high-voltage isolation circuit, voltage-controlled gain amplification circuit and high-speed ADC.
The high-voltage isolation circuit protects the receiving amplification circuit during transmission from high-voltage transmission pulse damage.
Voltage-controlled gain amplification circuit amplifies weak ultrasound echoes and transmits them to ADC for analog-to-digital conversion. It converts ultrasound echoes to digital signals for succeeding digital processing.
Voltage-controlled amplification circuit and high-speed ADC are all integrated in one AFE chip in M6.An AFE chip consists of 8-channel voltage-controlled gain amplification circuit and high-speed ADC. There are 8 AFEs in M6, composing 64 receiving channels.
4.2.2.3 Clock Circuit
The clock circuit provides low phase noise clock to the above-mentioned modules.
The clock circuit consists of crystal oscillator and clock allocator. The crystal oscillator is a 160Mhz oscillator with good phase noises. It distributes the clock signals via the clock allocator. The clock allocator has 12 LVDS outputs, and each one can split the frequency independently.

4.2.2.4 Signal Processing
The signal processing is mainly implemented through two FPGAs: FPGA1 and FPGA2.
The FPGA1 mainly responsible for controlling on the front-end chips (such as channel selection CPLD, VGA gain control DAC, ADC, transducer and transducer extend module), beam forming, and orthogonal demodulation, generating transmission sequence pulse, etc.
The FPGA2 implements signal processing, data uploading, real time scan parameters loading, 4D controlling, etc. Data is uploaded through PCIE interface.
4.2.2.5 Power Management
Power management is basically implemented by the power management FPGA.
System power can be sorted as STANDBY power, CPU STANDBY power and normal working power in terms of power-on sequence.
STANDBY power is provided in the status of system POWERDOWN, including 3V3STB and 1V5_FPGA.These power supplies are mainly for powering the power managing FPGA devices for power management. The power of power managing FPGA reset signal, 10k crystal oscillator, power managing FPGA, CPU12V_OK and CPU5VSTB_OK, etc. As long as the adapter is connected or batteries are loaded, they will be powered.
CPU STANDBY power is required in the POWER DOWN status of PC module, including 5VSBY and 3V3_STB_CPU.In the system is POWER DOWN, this power is turned off. Turn on this power before starting the PC system.
The working power is provided when the system is working normally. Except the two types of powers mentioned above, other powers all belong to working powers. The following indicators are used for the working powers:
Table 4-7 Power indicators on main board
There are some indicators on the control panel for indicating power status. The signals are described in the following table:
