Notes
1. Data rate:
Fast enable is achieved by setting input FEIN to LOW. This
signal is used to control fast switching on the digital
YUV-bus. HIGH on this pin forces the Y and U/V outputs
to a high-impedance state. The signal FEON is LOW when
the Y and U/V outputs are in this high-impedance state
(Fig.5).
The quoted frequencies are valid on the YUV-bus. The
time frames are controlled by the HREF signal.
