Wide Discriminator MM1327
Note 1 :
*
1 Clamp level and MAX output pin voltage
Measure voltage on each pin when GPIN and HDIN are connected to V
CC
.
Note 2 :
*
2 Y input voltage gain
Input a sweep signal to Y input, input a clamp pulse synchronized to H
SYNC
to GPIN pin, and
measure voltage gain at MAX pin for 100kHz.
Note 3 :
*
3 I, Q max/min gain
Input a square wave signal as shown below and a GPIN signal to I input (or Q input) and GPIN
pin, and measure voltage gain at MAX pin.
Note 4 :
*
4 MAX amp limit level
Measure limit level at MAX pin when LIMIT-SW pin is high. However, the limit range is as follows
for the NTSC/PAL pin.
Note 5 :
*
5 Offset voltage for reset
Connect GPIN pin to V
CC
and measure potential difference between INT IN pin and INT OUT pin.
Note 6 :
*
6 Integrated limit voltage
Input a 100% white signal to Y input and a clamp pulse synchronized to H
SYNC
to GPIN pin.
Measure INT OUT pin voltage at integration end at this time.
