   * You can safely ignore pins 3, 5 and 7.
   * All the parts are small enough to fit in a DB9 connector.

+  * The LM1881 circuit is useful to generate a composite sync signal from a composite video signal. Connecting a c-sync signal to the input of an LM1881 may cause problems and should be avoided.
