Difference between DSP mode (MODE = N.C. or 0) and
C (MODE = 1) mode:
In C mode, FS needs to be held low until all 16 data bits have been transferred. If FS is driven high before
the 16th falling clock edge, the data transfer is cancelled. The DAC is updated after a rising edge on FS.
In DSP mode, FS needs to stay low for 20 ns and can go high before the 16th falling clock edge.
In DSP mode there needs to be one falling SCLK edge before FS goes low to start the write (DIN) cycle. This
extra falling SCLK edge has to happen at least 5 ns before FS goes low, tsu(CK-FS) ≥ 5 ns.
In C mode, the extra falling SCLK edge is not necessary. However, if it does happen, the extra negative
SCLK edge is not allowed to occur within 10 ns after FS goes HIGH to finish the WRITE cycle (tsu(FS-C17)).
The maximum serial clock frequency is given by:
The maximum update rate is:
Note, that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
DAC has to be considered also.
The 16-bit data word consists of two parts:
Address bits (D15…D12)
Data bits (D11…D0)
