PACGAME-1
SCHEMATIC CONFIGURATION
Features
Integrated network contains 15 resistors,
10 capacitors, and ESD diodes.
Product Description
The signals to and from the MIDI/Game-port controller contain high frequency EMI signals that must be reduced before the
connector. Likewise, the signals from the Midi/Game-port controller must be protected from any possible external charges such
as static electricity. The PAC
TM
GAME-1 provides filtering and pull-up termination of the Game Port as well as ESD protection.
Application
EMI/RFI Filtering and ESD protection for
MIDI/Game port.
