DAC1617D1G0
Dual 16-bit DAC: up to 1 Gsps; x2, x4 and x8 interpolating
[1]
Bits CDI_MODE[1:0] of register MISC_CNTRL (see
Table 58
).
[2]
Bits INTERPOLATION[1:0] of register TXCFG (see
Table 23
).
[3]
If a Single Sideband Modulator (SSBM) is used, see bits NCO_ON and MODULATION[2:0] of register TXCFG (see
Table 23
).
[4]
Pins CLKP and CLKN (see
Figure 2
).
[5]
Bit PLL_PD of register PLLCFG (see
Table 24
).
[6]
Bits PLL_DIV[1:0] of register PLLCFG (see
Table 24
).
10.7.2
CDI mode 1 (x4 interpolation)
CDI mode 1 (
4 interpolation) is required when the values of the LVDS DDR clock and the
internal CDI frequency are equal.
Table 13
shows examples of applications using an
internal PLL or an external clock for the DAC core.
