2) Clock timing when the OSD function is used
Eight-color OSD color with a burster trimmer stacker fea-
ture can be used, simply by connecting an OSD with
external clock input. Output from the PIXCLK pin of the
BU1425AK should be input to the OSC-IN of the OSD IC.
The OSDSW input pin can be used as a signal for the
burster trimmer stacker feature called VBLK, or a similar
name. (See page 13 for a table showing the correspon-
dence between input data and color output.)

Fig. 15 Clock timing with the OSD function
The frequency of the PIXCLK pin output is one-half that of the internal clock. This phase is determined at the rising
edge of HSY, as shown in Fig.15. (In the Encoder Master mode, phase correction is implemented using the HSY
output of the BU1425AK itself.) The OSD function is effective only during the time that video output is enabled.
(See the TV signal timing diagram on page 27.)
