Three Realization Methods of Domestic Chip HT1200M Clock
As we all know that HART communication chip A5191HRT needs 460.8KHz passive crystal to run, as the perfect compatible chip of A5191HRT, HT1200M also needs 460.8KHz passive crystal for the chip to use. HT1200M chip development using the clock usually have three methods, respectively, the use of exter
