NXP Semiconductors Product data sheet
PECL termination PSSI3120CA
FEATURES
Single channel PECL termination in a th ree pin SOT23
package
ESD protection >2 kV
Undershoot protec tion
High capacitance range.
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
electros tatic disch arge (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 capaci tor is protected from damage due to
ESD by the diodes. The product is designed to enhance
signal integr ity in clock di stributio n network s. Addition ally,
it can be us ed as a termination in di gital transmission lines
where its inherent ESD protection helps maintain signal
integrity by reducing undershoots.
