DAC37J84: Timing requirements

Nobuhiko Wasa

Part Number: DAC37J84

Hello team,

My customer asks why there are typical values for "6.8 Timing Requirements" section in DAC37J84 datasheet. Is there any reason? How should the customer deal with those?

Thanks,
Nobuhiko Wasa

Nobuhiko,

If these requirements are not meet, the part will not operate properly. The SYSREF input has to meet a setup and hold time requirement with respect to the DACCLK. The serial interface will not work if the timing does not match the data sheet requirements.

Jim

Hi Jim,

In order that customer meet device requirements for operating properly, customer want to know min and/or max of timing parameters. But only typical parameters are present. Customer's questions are;
- Is there any special reason we don't specify max and/or min?
- If no special reason, please specify those.

Nobuhiko,

I have no idea why only the typical values were specified. The mins and maxs are not available.
