MB3514
Description
MB3514 encoder that receives analog composite synchronous signals outputs NTSC composite video signals. (luminance) (chrominance) signals analog signals also output. MB3514 incorporates matrix circuit, balanced modulator, signal mixer signals. generates various signals required encoding, which makes suitable personal computers.
24-pin plastic (FPT-24P-M01)
Features
Compatible with NTSC Composite video, signal outputs Internal driver (for output composite video, signals) Half-H killer Burst signal generator single power supply power consumption: (Typical) 24-pin plastic
This device contains circuitry protect inputs against damage high static voltages electric fields. However, advised that normal precautions taken avoid application voltage higher than maximum rated voltages this high impedance circuit.
