3-CHANNEL VIDEO PREAMPLIFIER WITH OSD MIXING FUNCTION
FOR HIGH-RESOLUTION COLOR DISPLAYS
DESCRIPTION
M52337SP is a video preamplifier provided with OSD mixing function, and a semi-conductor IC having three channels of a built­in amplifier in the 110MHz band. Each channel has the functions of OSD blanking, OSD mixing, wideband amplifier, main and sub-contrast control, and main and sub brightness. Accordingly, it is structured to best fit the OSD­provided high-resolution display.

allows three channels to be variable simultaneously, and a sub which allows each channel to be variable independently. Each control pin can be controlled within a range of 0 to 5V.
A built-in feedback circuit inside IC provides a stable DC level at

ELECTRICAL CHARACTERISTICS TEST METHOD
SW/NO of signal input pin and SW/NO of pulse input pin, which have already been described in the electrical characteristics table, are omitted, and SW/NO of external power supply will only be described as follows: Sub-brightness voltages, V32, V27 and V22, which are always set to the identical value, are represented by V32 in the electrical characteristic table. In addition, sub-contract voltages, V4, V9 and V14, which are also set to the identical value, are represented by V4 in the table.
Icc circuit current
Conditions shall be as specified in the electrical characteristic table, and take measurements with ammeter A when SW1 is turned to the b side.
Vomax output dynamic range
Follow the following procedure to set V19.
13
1. Input SG1 to pin (pin or pin ), gradually raise V19, and read V19 voltage when the upper part of the output waveform of T.P25 (T.P30 or T.P35) is distor ted to let the reading be VTR1 (V
TG1 or VTB1).
In addition, gradually reduce V19 conversely, and read V19 voltage when the lower part of the output waveform of T.P35 (T.P30 or T.P25) is distorted to let the reading be V VTB2).
