NB6L72
2.5V / 3.3V Differential 2 X 2
Crosspoint Switch with
LVPECL Outputs
Multi-Level Inputs w/ Internal Termination
Description
2 Crosspoint Switch with internal source termination and LVPECL
output structure, optimized for low skew and minimal jitter. The
differential inputs incorporate internal 50 W termination resistors and
will accept LVPECL, CML, LVDS, LVCMOS, or LVTTL logic levels.
The SELECT inputs are single-ended and can be driven with
LVCMOS/LVTTL.
when externally terminated with a 50 W resistor to V
performance clock and data management products.
