8 Bit Thevinin Termination Set
Compliant for LVPECL Termination
Excellent High Frequency Performance
Slim BGA Package
1% Resistor Tolerance
Low Channel to Channel Cross Talk
RoHS Compliant Designs Available
performance line termination for 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.
