XilinxFPGA可以选择端接电阻是在FPGA内实现还是外部实现,一般都是采用在FPGA内实现可以省却PCB上布板的不便,对接口速率较低的来说,有时候不端接也看不出问题来,但是速率一高问题就容易出现了,会影响到FPGA接收数据的准确性,就是信号完整性方面的内容。
管脚配置中off-chip termination和IN TERM \ OUT TERM分别指什么啊?,Xilinx FPGA可以选择端接电阻是在FPGA内实现还是外部实现,一般都是采用在FPGA内实现可以省却PCB上布板的不便,对接口速率较低的来说,有时候不端接也看不出问题来,但是速率一高问题就容易出现了,会影响到F
off chip termination fd_100Keil v5 STM32F756 off-chip RAM1配置后从on-chip flash启动不成功是什么原因?我的板子上主芯片是F756ZGT6. 板子上有颗 8M SDRAM芯片,地址是从0xC0000000 --0xC0800000 ,目前程序中可以正常访问。今天我把Keil v5中的配置加上off-chip RAM1 后,重新编译,居然发现 程序不能...

片外驱动调校OCD(Off-Chip Driver) OCD是在DDR-II开始加入的新功能,而且这个功能是可选的,有的资料上面又叫离线驱动调整。OCD的主要作用在于调整I/O接口端的电压,来补偿上拉与下拉电阻值,从而调整DQS与DQ之间的同步确保信号的完整与可靠性。调校期间,分别测试DQS高电平和DQ高电平,以及DQS低电平和DQ高电平的同步...
Placing the gate-line termination off-chip results in an S-21 flatness reduction, compared to the gain of a TWA with on-chip termination. Gain fluctuation over frequency is reduced by 4-8 dB when the termination resistor is placed as an external circuit.Progress in Artificial Intelligence...
