BU2878FS - On-screen Display

Description

Pin No.

The synchronizing signal is used to determine the presence or absence of a video signal, and the result is output on this pin (sync detect).

Pin5 is "L" when a signal is detected, and "H" when no signal is detected.

Features

  • 1)10 line X 24 character display. 2)64 (BU2878FS) or 128 (BU2871FS) character types. 3)For each line, the character size can be selected as either 1X or 2 X . 4)Characteroutputfor composite video is white with black border. 5)Background color can be either white black or blue (black or white with PAL systems).
  • A b s o l u t e maximum ratings (Ta=25°C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Symbol Vcc 6)Built-in synchronous separatio.
