DSPQuestion
- 做DSP最应该懂得157个问题(回答) 四.5V/3.3V如何混接? TI DSP的发展同集成电路的发展一样,新的DSP都是3.3V的,但目前还有许多外围电路是5V的,因此在DSP系统中,经常有5V和3.3V的DSP混接问题。在这些系统中,应注意: 1)DSP输出给5V的电路(如D/A),无需加任何缓冲电路,可以直接连接。 2)DSP输入5V的信号(如A/D),由于输入信号的电压>4V,超过了DSP的电源电压,DSP的外部信号没有保护电路,需要加缓冲,如74LVC245等,将5V信

- 我们对处理速度的需求日益增长,伴随着这种增 长,用来构建单片机的晶体管尺寸则在持续减小。 以更低的成本实现更高的集成度,也促进了对更小 的几何尺寸的需求。随着尺寸的减小,晶体管击穿 电压变得更低,最终,当击穿电压低于电源电压 时,就要求减小电源电压。因此,随着速度的提高 和复杂程度的上升,对于高密度器件而言,不可避 免的后果就是电源电压将从 5V 降至 3.3V,甚至 1.8V。-We are increasing the demand for processin
