NB6L72M
2.5V / 3.3V Differential 2 X 2
Crosspoint Switch with
CML Outputs
Multi- Level Inputs w/ Internal Termination
Description
The NB6L72M is a clock or data high-bandwidth fully differential
2 x 2 Crosspoint Switch with internal source termination and CML
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 16 mA differential CML outputs provide matching internal
50 W terminations and 400 mV output swings when externally
terminated with a 50 W resistor to V
CC
.
The device is offered in a small 3 mm x 3 mm 16-pin QFN package.
The NB6L72M is a member of the ECLinPS MAX™ family of
high performance clock and data management products.
