PRODUCT SPECIFICATION

Horizontal Timing
Horizontal line rate is selectable, and is determined by the
FORMAT control bits (12.27 Mpps for NTSC, 13.5 Mpps
for NTSC and PAL). Figure 5 illustrates the horizontal
blanking interval. Figure 6 completes the definition of timing
parameters with vertical blanking interval detail.

Programming the TMC22071A
Upon power-up after bringing RESET LOW, the
TMC22071A Control Register is set to default values as
shown in the top entry of Table 3. These default values do
not necessarily render the TMC22071A operational in any
specific application. Before the TMC22071A is expected to
acquire input video, its Control Register must be loaded with
data that is specific to its use.
