LVPECL Terminators
Technical Data Sheet
RoHS Compliant Parts Available
Description
These integrated termination networks provide high
performance line termination designs for both 2.5V & 3.3V
LVPECL busses.
Specifically designed shielding inside the package combined
with a ceramic substrate virtually eliminates cross talk between
channels that is common in other termination networks and
resistor arrays.
The BGA packaging has been proven to reduce rework and
improve reliability.
