MOTOROLA ANALOG IC DEVICE DATA
pulse generated from the flyback or from an MCU. The
threshold level of 1.25 V. The blanking pulse width should be
equal to the flyback retrace period to make sure that the
video signal is blanked properly during retrace. It is
necessary to limit the amplitude, and avoid any negative
undershoots if the flyback pulse is used. This Blanking input
pin cannot accept a negative voltage. This pin should be
grounded if it is not used.
OSD interface
Figure 3 show a typical application with an OSD device
(MC141540). The MC141540 OSD and FC outputs are TTL
compatible, and therefore interface directly with MC13282A.
Level shifting circuitry is not needed. The MC141540 is a
digital device, controlled by an MCU. Therefore, separate
power supply runs to the MC141540 and to the MC13282A
are recommended. Care should be taken in the PC board
layout to prevent digital noise from entering the analog
portions of MC13282A.
Normally the OSD switching is done during the active
video time. It is recommended that the Fast Commutate pin
not be activated during the horizontal sync time.
