Recently, the total investment of 120 million yuan, the annual output of 5 megawatts of photovoltaic power generation board production line and semiconductor lighting projects completed the environmental assessment and other approval procedures, will be in Jining Jiaxiang County Maji Industrial Park. After the project is completed, it will fill the blank of photovoltaic power generation board production line and semiconductor lighting project in Shandong Province, realize annual sales income of 200 million yuan, and realize profits and taxes of 30 million yuan.
Jiaxiang relies on the high-tech zone to actively carry out investment in new energy and new light source industries such as LED, and plans to build LED industry gathering areas. At the same time, study and implement policies and measures to support the development of low-carbon economy, vigorously develop low-energy, low-pollution, low-emission enterprises, cultivate a number of circular economy pilot enterprises, and strive to build a low-carbon economy demonstration zone.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
SCSI-3
In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
