GENERAL DESCRIPTION

The Controlled Capacitance TransGuard is an application specific bi-

directional transient voltage suppressor developed for use in mixed signal

environments. The Controlled Cap MLV has three purposes: 1) reduce

emissions from a high speed ASIC, 2) prevent induced E fields from

conducting into the IC, and 3) clamp transient voltages

By controlling capacitance of the MLV, the center frequency and 20db

range for filtering purposes can be targeted. A Controlled Cap MLV can

greatly improve overall system EMC performance and reduce system

size.
