DAC1205D750
Dual 12-bit DAC, up to 750 Msps; 4x and 8x interpolating
10.4 Input clock
The DAC1205D750 can operate at the following clock frequencies:
PLL on:
up to 185 MHz in Dual-port mode and up to 370 MHz in Interleaved mode
PLL off:
up to 750 MHz
The input clock is LVDS compliant (see
Figure 8
) but it can also be interfaced with CML
differential sine wave signal (see
Figure 9
).
10.5 Timing
The DAC1205D750 can operate at a sampling frequency (f
s
) up to 750 Msps with an input
data rate (f
data
) up to 185 MHz. When using the internal PLL, the input data is referenced
to the CLK signal. When the internal PLL is bypassed, the SYNC signal is used as a
reference. The input timing in the second case is shown in
Figure 10
.
