一、问题的提出在高速计算机的研制中,电路是基础,它直接影响到机器的稳定性和可靠性。对MECL10K 高速电路,我们除了严格按厂家手册所规定的条件测试:组件建立了热平衡后,室温25℃,横向风速大于150米/分,输出经一50Ω电阻端接到-2.0V。测试项目也按手册规定的进行测试。为了充分发挥现成电路的潜力,我们增加了直流电平分挡以提高电路的抗干扰能力和平均延迟时间 t_(pd)分挡测试,还增加了电源电压
First, the question raised In the development of high-speed computer, the circuit is the foundation, it directly affects the stability and reliability of the machine. For the MECL10K high-speed circuit, we test strictly according to the manufacturer’s manual. After the components have been heat-balanced, the room temperature is 25 ℃ and the wind speed in the horizontal direction is more than 150m / min. The output is connected to -2.0V through a 50Ω resistor. Test items are also tested according to the provisions of the manual. In order to give full play to the potential of off-the-shelf circuits, we increased the DC level of the sub-block to improve the circuit’s anti-interference ability and average delay time t_ (pd) split test, but also increased the supply voltage
