MC13077, ADVANCED PAL/NTSC ENCODER

Pin 1 2 Symbol VCC Comp Video 75 Ω Zo = 75 Ω 75 Ω 1.0 kΩ Internal Equivalent Schematic Description Supply Voltage Composite Video output.

The external 75 Ω series resistor determines the impedance of the output.

The output will drive a 75 Ω load through a 75 Ω coax.

Order this document by MC13077/D MC13077 Advanced PAL/NTSC Encoder The MC13077 is a high quality RGB/YUV to NTSC/PAL encoder with Composite Video and S Video outputs.

The IC integrates the color difference and luma matrix circuitry, chroma modulators, subcarrier oscillator, and logic circuitry to encode component video into a composite video signal compatible with the NTSC/PAL standards.

The IC operates off a standard + 5.0 V supply and typically requires less than 75 mA, making it usef

MC13077 Features

* If not used as an input the pin is clamped during sync to 2.4 Vdc. Can be used as a B

* Y input (AC coupled, 350 mVpp, 100% color saturation). Burst Flag, if disabled at Pin 18, must be inserted here with the following signal levels;

* 170 mV (NTSC),

* 121 mV (PAL). If not used
