Philips Semiconductors Product specification

PECL termination PSSI3120CA

FEATURES

• Single channel PECL termination in a three pin SOT23
package

• ESD protection >2 kV

• Undershoot protection

• 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) clocktermination with integrated diodes, providing
electrostatic discharge(ESD) protection up to2 kV. Using
thinfilm-on-silicon technologythe PSSI3120CAintegrates
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 canbe usedas a terminationin digitaltransmission lines
where its inherent ESD protection helps maintain signal
integrity by reducing undershoots.
