OPTION
(Conditions)
l
The starting point of external partial signal is 32.5H from the falling edge of ex-VD.
l
The external partial signal is controlled at each ex-HD falling edge. Set the start / finish of
the external partial signal in 1H increments.
l
The number of 1H high-speed transfer line is 18 lines. The actual lines are determined by the
external partial signal “hi” length. (Minimum: 2H = 36 lines)
l
After high-speed transfer, 2H is allocated to blank transfer period. Normal transfer starts at
the next line.
l
VIDEO OUT vertical blanking is;
V blanking = 32.5(H) + n(H) + BLK transfer [2(H)] – 1H
*An example follows below.
(High-speed minimum 2H = 36 lines)
l
The function/features noted as “option” or shown with the OPTION mark in this document is
available as optional function/feature (= Production on order) and not provided as standard
function. Please contact our sales staff for details.
