FPGA/ASIC DAC DRIVER REQUIREMENTS
To achieve data synchronization using the high speed capability of
the AD9736, ADI recommends the configuration in Figure 35 for
the FPGA/ASIC driving the digital inputs. Using the Double Data
Rate DATACLK_OUT, this configuration will generate the LVDS
DATACLK_IN to drive the AD9736 at the DDR rate. The circuit
also synchronizes the DATACLK_IN and the digital input data
(DB<13:0>) as required by the AD9736. The synchronization
engine in the AD9736 then uses DATACLK_IN to generate the
internal CLOCK SAMPLING SIGNAL to capture the incoming
data via the Manual, Surveillance or Auto mode.
To operate in 2x mode, the circuit in Figure 35 must be modified to
include a divide-by-two block in the DATACLK_OUT path.
Without this additional divider the DATA and DATACLK_IN will
be running 2x too fast. DATACLK_OUT is always DACCLK/2.
