PACGAME1
MIDI (Musical Instrument Digital Interface) /
Game Port Filter/Protection Circuit
Features
Integrated network contains 15 resistors,
10 capacitors, and ESD diodes
ESD protection to greater than +4kV
(MIL-STD-883 Method 3015) and greater
than +8kV in-system
Applications
Personal computers and gaming devices requiring
EMI/RFI filtering and ESD protection for MIDI/
Game Ports in a single package.
Product Description
The PACGAME1
TM
provides EMI filtering, pull-up ter-
mination and ESD protection for Game Port interfaces
in one convenient device. The signals to and from a
MIDI/Game Port controller generally contain high fre-
quency components that emit unwanted EMI at the
connector. Likewise, the signals from the MIDI/Game
Port controller must be protected from any possible
external electrical discharges typically caused by static
electricity. The PACGAME1 provides these functions
as well as a selectable pull-up function.
