正射极耦合逻辑(PECL)是成帧器高速I/O的标准逻辑电平,这种输出方式耗电较大,为降低功耗需采用一些间接的解决方案。Maxim推出的MAX3881、MAX3891复用/解复用器的并行通道采用单端PECLI/O,可有效解决上述问题,但在单端与差分接口之间
The positive emitter coupled logic (PECL) is the standard logic level for the framer high-speed I / O. This type of output consumes a lot of power and requires some indirect solution to reduce power consumption. Maxim introduced MAX3881, MAX3891 multiplexer / demultiplexer parallel channel single-ended PECLI / O, which can effectively solve the above problems, but in between single-ended and differential interface
