MC13077 - ADVANCED PAL/NTSC ENCODER

General Description

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.

Key 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 as an input the pin is clamped during sync to 2.4 Vdc. Can be used as a R.
  • Y input (AC coupled, 490 mVpp, 100% color saturation). Burst Flag, if disabled at Pin 18, must be inserted here with t.

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 useful in PC environments. The high degree of integration saves board space and cost, as only passive external components are required for operation. The IC is manufactured using Motorola’s MOSAIC™ process and is available in a 20 pin DIP or SOIC package. • Single 5.
