APPLICATIONS
Enhanced high speed clock line signal integrity for the
following:
• Workstations
• Desktop PCs
• Notebook PCs.
DESCRIPTION
Single channel, RC-type positive emitter-coupled logic
(PECL) clock termination with integrated diodes, providing
electrostatic discharge (ESD) protection up to 2 kV. Using
thin film-on-silicon technology the PSSI3120CA integrates
three resistors, one capacitor and two diodes in a SOT23
package. The capacitor is protected from damage due to
ESD by the diodes. The product is designed to enhance
signal integrity in clock distribution networks. Additionally,
it can be used as a termination in digital transmission lines
where its inherent ESD protection helps maintain signal
integrity by reducing undershoots.
