DESCRIPTION
The MB3516A is an RGB encoder containing an RGB signal matrix circuit, balanced modulator circuits, and a
luminance signal/color-difference signal mixing circuit. This device inputs analog RGB and composite sync signals
and outputs a composite video signal in the NTSC or PAL format. Also, it has Y/C separate output pins and RGB
signal output pins.
s
FEATURES
· Supporting for both of the NTSC and PAL formats
· Containing Y/C separate output and RGB output pins as well as a composite video signal output pin
· On-chip 75
driver (Composite video output, Y/C separate outputs, RGB outputs)
· Half H-killer circuit integrated
· Burst flag generator integrated
· PAL alternate circuit integrated
· Built-in filters
· Operation with a +5 volt single power supply
· Low power consumption: 280 mW (typical)

With CSYNC-IN at the "L" level, the R-IN, G-IN, and B-IN
pins are clamped. During the "L" level period, the R-IN,
G-IN, and B-IN pins input pedestal levels. (100% = 1 Vp-p)

ABSOLUTE MAXIMUM RATINGS
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
s
RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device's electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
