DAC1627D1G25
Dual 16-bit DAC: up to 1.25 Gsps; x2, x4 and x8 interpolating
10.5 Input clock
The DAC1627D1G25 operates with two clocks, one for the LVDS DDR interface and one
for the DAC core.
10.5.1
LVDS DDR clock
The LVDS DDR clock can be interfaced as shown in
Figure 10
because the clock buffer
contains a 100
Ω
internal resistor.
10.5.2
DAC core clock
The DAC core clock can achieve a frequency of up to 1.25 Gsps. It includes internal
biasing to support both AC-coupling and DC-coupling. The clock can be easily connected
to any LVDS, CML or PECL clock sources.
Depending on the interface selected, the hardware configuration varies
(see
Figure 11
to
Figure 13
).
