APPLICATION INFORMATION
The MC13081X is an integrated multisync color monitor
processor. It combines horizontal/vertical deflection processing
circuitry and video pre–amplifiers into a single device.
The overall timebase section consists of two parts:
horizontal and vertical. The horizontal timebase can be
operated from 30 kHz to 64 kHz, and can be driven from TTL
separate sync, composite sync, or a composite video signal.
There are two PLLs which ensure proper timing throughout
the whole system. The first PLL provides line locking of the
horizontal sync signal with the built–in oscillator, while the
second one maintains fixed timing with the horizontal flyback
signal such that a stable display can be achieved.
The vertical timebase section operates from 45 Hz to
100 Hz, and can receive various sync signals as the
horizontal one does. This section consists of an oscillator and
a ramp generator. Adjustments include linearity, ramp
amplitude, and minimum free running frequency in the
absence of sync signal.
The video section has three 70 MHz bandwidth
pre–amplifiers. The outputs of these amplifiers are
uncommitted collector/emitter facilitating cascode
configuration with subsequent stages. Controls include
brightness and contrast. In addition, the voltage gain of each
amplifier can be adjusted individually which provides
flexibility in adjusting color correctness. Blanking and
clamping signals are provided to the amplifiers internally from
the timebase section. Additionally, a blanking signal can also
be supplied externally.
Separate power supply and ground pins are provided to
the timebase and video section in order to minimize the cross
interference between these two sections.
