IP authentication platform based on PCI interface

The IP core verification platform uses ALTERA Cyclone series FPGA, model EP1C12Q240C8, which provides over 300,000 gates of system resources and 240k bit of internal high-speed FIFO, as well as two internal high-speed PLLs that can synthesize 10M to 200M system core clocks. For high-speed LVDS differential interfaces, large-scale applications can be optimized by QUARTUS design tools to achieve system operating frequencies in excess of 100MHz, meeting the needs of most users, and cost-effective.

The IP core verification platform adopts a 6-layer PCB design and uses an independent external clock synchronization chip to provide a stable zero-delay clock system circuit for PCI and other interfaces, meeting the clock requirements of the PCI bus, and making the verification platform high-speed, stable, and reliable. jobs.

Vacuum Circuit Breakers

High voltage Vacuum circuit breaker is an indoor power distribution device in the 3~10kV, 50Hz three-phase AC system, which can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for places requiring oil-free, less maintenance and frequent operation. The circuit breaker can be configured in the central cabinet, double-layer cabinet, and fixed cabinet to control and protect high-voltage electrical equipment.

Specifications:
1.Vacuum circuit breakers can usually be divided into several voltage levels. Low-voltage type is generally used for explosion-proof electrical use. Like coal mines and so on.

2.The rated current reaches 5000A, the breaking current reaches 50kA, and the voltage has reached 35kV.
