RGB ENCODER
MB3514
s
Description
The MB3514 is an RGB encoder that receives analog RGB and composite synchronous signals and outputs NTSC and PAL composite video signals. Y (luminance) and C (chrominance) signals and analog RGB signals can also be output. The MB3514 incorporates a matrix circuit, balanced modulator, and Y-C signal mixer for RGB signals. It generates various signals required for encoding, which makes it suitable for personal computers.
24-pin plastic SOP (FPT-24P-M01)
s
Features
* Compatible with NTSC and PAL * Composite video, Y and C, and RGB signal outputs * Internal 75 driver (for output of composite video, Y and C, and RGB signals) * Half-H killer * Burst signal generator * +5 V single power supply * Low power consumption: 275 mW (Typical) * 24-pin plastic SOP
This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit.
