MSP430F67641: The switching characteristics of SD24_B module.

Luke Chen

Part Number: MSP430F67641

Hello,

I don't see the switching characteristics information of SD24_B on datasheet, such as data setup time, hold time..etc, we need this information to select proper external modulator when using bit stream interface.

Please advise how can I get this timing data, thanks for help.

Hi Luke,

The parameters shown on Datasheet should be all we have for the SD24_B.

You could go through the section 29.2.7 Digital Filter of device User's Guide for the digital filter timing as you're planning to input an external bitstream to the internal digital filter.

Also, could you give me details about which specific parameters is required for your application? I can't understand the parameters "data setup time, hold time" you mentioned for a SD_ADC.

Hi Wei,

Digital filter interface should have spec of bitstream input/output timing requirement as below.

Actually communication ports should have this kind of timing spec, for example eUSCI, please refer to MSP430F67641 datasheet(SLAS998A) Table 5-30 for more information.

Please help me to get timing spec of digital filter, thanks.
