Standard Interface Circuit

In modulation driving circuit, with the chip MAX3263, being the function of APC, there is standard PECL level interface to modulate laser modulation current and preset current neatly.

在调制驱动电路中，采用MAX3263芯片，具备标准的PECL电平接口，可以灵活地调整激光器的预置电流和调制电流，并具备自动功率控制功能。

Adopt strict charge to manage the circuit, it can protect with overload, undervoltage, short circuit, etc. output for standard USB power supply interface.

采用最严格的充电管理电路，具有过载，欠压，短路等多重保护，标准usb电源接口输出。

As a try for circuit standardization, the system realizes the standard protection circuit unit and recovering-time circuit unit, which are connected to system through standard 44 pins' bus interface.

作为标准化的尝试，本系统实现了标准的保护电路单元和恢复时间电路单元，通过44芯总线插座与标准总线接口连接。
