【选型】通信速率最高达150Mbps的芯科4通道数字隔离器可PTP替代ADuM1411ARWZ,性能更优
某项目客户使用ADuM1411ARWZ由于该料缺料严重,交期较长,现需要PIN TO PIN替代,本文重点介绍SILICON LABS 4通道数字隔离器Si8641BD-B-IS可PIN TO PIN 替代ADuM1411ARWZ。Silicon Labs 4通道数字隔离器Si8641BD-B-IS可支持最高150Mbps的通信速率,隔离电压最高可达5000VRMS,而且还具有精确的时间参数,其通道的传播延迟仅10ns,传播延迟抖动为2ns,最小脉宽可达5ns。图一是两个器件电气参数对比。

从以上参数可以得知供电电压范围更宽,通信速率更高,瞬态抗扰度更高,工作温度范围更高,而且有车规和安规双认证,所以可以用在汽车电子等高要求行业,其它参数一致可以替代。
以下是两个器件引脚示意图:

以下是两个器件引脚定义图:
Si8641BD-B-IS
ADuM1411ARWZ
从上图得知两个器件中脚定义一致,可以替代。综上所述,Silicon Labs 4通道数字隔离器Si8641BD-B-IS可PIN TO PIN 替代ADuM1411ARWZ。

请推荐高速IO电平转换芯片,用于3.3vMCU产生5V的IO信号,用于高速SPI。
可以采用数字隔离芯片实现电平转换,例如隔离芯片源边连接3.3V电源,副边连接5V电源,实现电平装换,Silicon labs的数字隔离芯支持150MHz速率,对于SPI通信可以选用Si8641,3路输入(对于Si8641的源边),用于MOSI、CLK和片选信号,一路输出用于MISO信号。

有没有自带隔离DC-DC的数字芯片应用在SPI通讯应用上?
推荐高速数字隔离Si88241,它自带DC-DC电源控制器,外部只需接个小型变压器即可实现电源转换,4通道数字隔离,三进一出,非常适合SPI通讯的应用场合。
SI8400AB是I2C的双向数字隔离器,是否可以直接用于SPI的信号电平转换??
1、Si8400是Silicon Labs公司的数字隔离器件,用于I2C通信隔离设计,速率1.7Mbps。如果用于SPI通信的话,推荐使用Si8641,具备4通道隔离,满足SPI的通信隔离需求,最高速率150Mbps。2、推荐的型号有Si8641BD(默认输出低电平),Si8641ED(默认输出高电平)。这两个型号都是大批量的型号,有性价比和供货保障。3、Si8641数据手册:Si864x Low-Power Quad-Channel Digital Isolators Data Sheet
Si87XX容耦隔离器较Si86XX隔离器有何性能提升?
