ON-CHIP INTEGRATED OSCILLATOR CIRCUITSCHRISTOPHER J * BEALE
,配置时时钟以前选择的是RTC倍频,现在发现RTC倍频改为on-chipUSB oscillator,请问on-chipUSB oscillator 这个时钟是由外部提供还是内部自带的? 2:项目没有使用EMIF ,那EM_WAIT2-EM_WAIT5是否可以悬空?谢谢! zixiang_huang2019-02-12 11:33:49 关于AI背景下的on-chipESD (静电保护)需求分析和应用 ...
The design uses a relaxation oscillator with fully integrated elements so no external components are required. The oscillator is designed to have excellent supply noise rejection so it is ideal for use in noisy SoC environments. View Free-running on-chip oscillator full description to... see ...
on-chip integrated optical modulators can be considered as next-generation ultra-compact modulators to overcome the drawbacks of AOMs mentioned-above and meet higher requirements in terms of device size and power consumption. Chip-scale AOMs are being intensively studied to explore acoustic-optic intera...
