AMC1306M05: Difference between AMC1306 and AMC1204

Part Number: AMC1306M05
Other Parts Discussed in Thread: AMC1204

Dear Teams,

My customer is asking the difference between AMC1306 and AMC1204 based on AMC1306's manchester coding feature. Based on what I know so far, AMC1306 with manchester coding can save the data and clock line. Apart from that, what else advantages the manchester coding can introduce that perform better than AMC1204?

Thanks!

Hi Dylan,

Aside from the Manchester coding feature, the AMC1306 has high isolation specifications and a couple of different input ranges to fit with a wider range of shunt resistors. Because of this the AMC1306 will be capable of better performance than the AMC1204 in some systems.

The main advantage of the Manchester coding as you mentioned is that only one line is needed between the modulator and the digital filter. Another advantage is that since the clock signal is encoded in the data line there is no chance of the data being unsynchronized from the clock. For example, with a separate clock and data line if the clock trace is significantly longer or shorter than the data trace, the data may not line up properly with the clock edges and cause the filter to take in the data incorrectly, introducing error. Manchester encoding avoids this.

Regards,

Scott

Hi Cummins,

Really appreciated for your information. I have explained all the detail to my customer, and they are wiling to change the solution to AMC1306.

Thanks!
