NB6L72
2.5V / 3.3V Differential 2 X 2
Crosspoint Switch with
LVPECL Outputs
Multi-Level Inputs w/ Internal Termination
Description
The NB6L72 is a clock or data high-bandwidth fully differential 2 x
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.
The differential LVPECL outputs provide 800 mV output swings
when externally terminated with a 50 W resistor to V
CC
– 2.0 V.
The device is offered in a small 3 mm x 3 mm 16-pin QFN package.
The NB6L72 is a member of the ECLinPS MAXt family of high
performance clock and data management products.
