Driving the CLI Input
The AD9847’s master clock input (CLI) may be used in two
different configurations, depending on the application. Figure 23a
shows a typical dc-coupled input from the master clock source.
When the dc-coupled technique is used, the master clock signal
should be at standard 3 V CMOS logic levels. As shown in
Figure 23b, a 1000 pF ac-coupling capacitor may be used between
the clock source and the CLI input. In this configuration, the CLI
input will self-bias to the proper dc voltage level of approximately
1.4 V. When the ac-coupled technique is used, the master clock
signal can be as low as
±500 mV in amplitude.

Internal Mode Circuit Configuration
The AD9847 may be used in internal mode using the circuit
configuration of Figure 24. Internal mode uses the same circuit as
Figure 21, except that the horizontal pulses (CLPOB, CLPDM,
PBLK, and HBLK) are internally generated in the AD9847.
These pins may be grounded when internal mode is used. Only
the HD and VD signals are required from the ASIC.
