M52759SP
UNIFORMITY FOR CRT DISPLAY MONITOR
DESCRIPTION
M52759SP is Semiconductor Integrated Circuit
for uniformity of CRT Display Monitor.
It generates horizontal and vertical parabola waves and
is able to revise contrast of CRT Display Monitor if it is
used with Video Pre. Amp. M52742SP that has uniformity
circuit .
FEATURES
• It can control phase of horizontal wave.
• It can changes the parabola wave unbalance .
• It contains the horizontal saw wave generator and Auto
Gain Control circuit , so that it is able to keep the amplitude
constant if frequency change.
• It can changes the parabola wave unbalance .
• Frequency Band Width: horizontal 24 to 120kHz
vertical 50 to 185Hz
• Input: horizontal 5Vp-p Pulse
vertical 3.2 Vp-p V Saw

The way to measure
No1.ICCH Measure the input current to Pin-10.
No2.ICCV Measure the input current to Pin-20.
No3.VREF Measure the output voltage at Pin-14
No4.VREF Measure temperature drift of Pin-14 .(-20°C to 85°C )
No5.VIL Input Signal to Pin-17
5.0V
2.0V
Output Signal at Pin-7
Input horizontal pulse which low level is 2V in Pin-17 and confirm output horizontal
signal at Pin-7.
