说明
HV7321是一款4通道、5电平超声波发射器,内置T/R开关、输出保护二极管和箝位二极管。HV7321可提供高达±2.5A的电流,输出电压摆动可高达±80V。HV7321同时支持透明和重新计时模式。重新定时的时钟频率可以支持高达220MHz的频率。重新定时功能有助于减少由驱动场可编程门阵列(FPGA)引入的输出抖动。
HV7321有两种不同的CW传输模式,CW模式0和CW模式1。在CW模式0(模式=0,PWS=0)中,VPP1和VNN1轨道用于CW传输。输出电流在CW模式-0中减小。在CW模式1中,HV7321接受外部CW波束形成器的输出作为CW源。HV7321与LVCMOS 2.5V/.3V输入兼容,可以直接与FPGA接口。HV7321有9毫米x 9毫米64引脚VQFN封装。
