Internal Mode Circuit Configuration
The AD9848/AD9849 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
AD9848/AD9849. These pins may be grounded when Internal
Mode is used. Only the HD and VD signals are required from
the ASIC.
