About the output timing of DAC3152.

Guru 19495 points
Other Parts Discussed in Thread: DAC3152

Please let me know below about the output timing of DAC3152.

 

--------------------------

The following is written on the 7&14th page of the datasheet.

・Ach is a rising edge of DACCLKP.

・Bch is a falling edge of DACCLKP.

・Latency is typ 1.5 cycle. (Input=>Output)

 

In this case, the timing of output:(1) or (2),which is right?

(1):The output is update simultaneously about IOUTA/B.

(2):The output side is update individually about IOUTA/B.

※The image figure should look at attachment.

--------------------------

 

Best regards,

Satoshi

  • Hi Satoshi,

    The outputs are updated simultaneously, so (1) is correct, however the 1.5 cycle latency is referenced to the capture of the A channel data with the rising edge of the clock. See the digital diagram below as a reference.
