Electrical Characteristics (CONTROL part)
(Ta=25
°
C unless otherwise specified)
Notes:
(1) These parameters, although guaranteed, are not 100% tested in production
(2) These parameters, although guaranteed, are tested in EDS (wafer test) process
(3) The amplitude of the sync. pulse is recommended to be between 2V and 3V for stable sync. function.
