3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING DESCRIPTION
The M52734SP is a semiconductor integrated circuit amplifies video signals, having a 3-channel amplifier with a band width of 130MHz. The circuit also features the OSD mixing function. The circuit is most useful with high resolution displays that have OSD, and its function are available for each channel, including OSD blanking, OSD mixing, wide-band amplification, contrast control (main and sub), and brightness control.

To adjust contrast, two types of controls are provided, main and sub. With the main control, the contrast of the 3-channels can be changed simultaneously. Sub controls are used to adjust the contrast of a given channel individually. The control terminals can be controlled by applying a voltage of 0 to 5V. The DC power remains stable at the IC output terminal because a feedback circuit is built in.

ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin switch numbers is already given in Supplementary Table, only external power supply switch numbers are included in the notes below. Sub contrast voltages V4, V9 and V14 are always set to the same voltage, therefore only V4 is referred to in Supplementary Table. ICC Circuit current Measuring conditions are as listed in Supplementary Table. Measured with an ammeter At test point A when SW1 is set to a. Vomax Output dynamic range Voltage V19 is varied as described below: 1. Increase V19 gradually while inputting SG6 to pin 13 (8 or 3). Measure the voltage when the top of the waveform output at T.P25 (30 or 35) is distorted. The voltage is called VTR1 (VTG1 or VTB1). Next, decrease V19 gradually, and measure the voltage when the bottom of the waveform output at T.P35 (30 or 25) is distorted. The voltage is called VTR2 (VTG2 or VTB2).
0.0 Waveform Output at T.P25 (Identical to output at T.P30 and T.P35.) 5.0 (V)
2. Voltage VT (VTR, VTG and VTB) is calculated by the equation below: VTR (VTG, VTB)= VTR1 (VTG1, VTB1) + VTR2 (VTG1, VTB1) 2
Use relevant voltages, depending on the pin at which the waveform is output; specifically, use VTR1 when it is output at T.P25; VTG1, at T.P30, and VTB, at T.P35.
