10.5 Timing
The DAC1405D650 can operate at an update rate (f
s
) of up to 650 Msps and with an input
data rate (f
data
) of up to 160 MHz. The input timing is shown in
Figure 10 “Input timing
diagram”
.
The typical performances are measured at 50 % duty cycle but any timing within the limits
of the characteristics will not alter the performance.
In
Table 31 “Frequencies”
, the links between internal and external clocking are defined.
The setting applied to PLL_DIV[1:0] (register 02h[4:3]; see
Table 9 “Register allocation
map”
) allows the frequency between the digital part and the DAC core to be adjusted.
Table 31.
Mode
The settings applied to PLL_PHASE[1:0] (register 02h[2:1]) and PLL_POL
(register 02h[0]), allows adjustment of the phase and polarity of the sampling clock. This
occurs at the input of the DAC core and depends mainly on the sampling frequency. Some
examples are given in
Table 32 “Sample clock phase and polarity examples”
.
