3-CHANNEL VIDEO PREAMPLIFIER PROVIDED WITH OSD MIX
AND RETRACE LINE BLK FOR HIGH-RESOLUTION
DESCRIPTION
M52722SP is a video amplifier provided with OSD mixing function, and a semiconductor IC having three channels of a built-in wideband 180MHz amplifier. Each channel has the functions of OSD blanking, OSD mixing, retrace line blanking, wideband amplifier, main and sub contrast control, and main brightness. Accordingly, it is structured to best fit the OSD-provided high resolution display. .

output amplitude 4.0VP-P when SGA is input, output amplitude VOR 8 (VOG8 or VOB8) when SG1 is input, and output amplitude VOR9 (VOG9 or VOB9),
frequency characteristics FC1 or FC1' is calculated from:
∆VB1=VOR7 VOG7 [V]
=V
OG7 VOB7
=VOB7 VOR7
V
B2 brightness control characteristics and
∆V
B2 relative brightness control characteristics (at typ.)
1. The conditions shall be as specified in the electrical characteristics table.
2. Use an ammeter to measure the output of T.P25 (T.P30 or T.P35) at this time to let the value be VOR7 (VOG7 or VOB7). This value represents VB2.

OR8(VOG8, VOB8) [VP-P]
4.0 [VP-P]
V
OR9(VOG9, VOB9) [VP-P]
4.0 [VP-P]
4. F or relativ e frequency bands ∆F in FC1 and FC1 for each channel.
