DAC1405D750
Dual 14-bit DAC, up to 750 Msps; 4 and 8 interpolating
[1] D = guaranteed by design; C = guaranteed by characterization; I = 100 % industrially tested.
[2] CLKP and CLKN inputs are at differential LVDS levels. An external differential resistor with a value of between 80 and 120 should
be connected across the pins (see Figure 8
).
[3] V
gpd
represents the ground potential difference voltage. This is the voltage that results from current flowing through the finite resistance
and the inductance between the receiver and the driver circuit ground voltages.
[4] IMD3 rejection with 6 dBFS/tone.
