Inputs
The MAX9508 video inputs YIN, CIN, and CVBSIN
should be directly connected to the output of the video
current DAC. DC-coupling ensures that the input sig-
nals are ground referenced such that the sync tip of
composite or luma signals is within 50mV of ground
and the blank level of the chroma signal is between
0.5V and 0.65V. Since the input buffer is identical for
YIN, CIN, and CVBSIN, any standard-definition video
signal can be applied to those inputs as long as the
signal is between ground and 1.05V when V
DD
= 2.7V.
For example, three composite video signals could be
applied to YIN, CIN, and CVBSIN. The RGB set and the
YPbPr set can also be inputs to YIN, CIN, and CVBSIN
(Figure 9).
The EXTCVBSIN input can only handle signals with a
sync pulse, such as composite, video, or luma.
Because the DC level of an external video input signal
is unknown, the external video signal is AC-coupled
through a 0.1μF capacitor, and a sync tip clamp sets
the internal DC level of the MAX9508. A 2:1 multiplexer
under the control of the
INT
/EXT input selects either the
signal at CVBSIN or EXTCVBSIN.
