NB6L72
2.5V / 3.3V Differential 2 X 2
Crosspoint Switch with
LVPECL Outputs
Multi−Level Inputs w/ Internal Termination
http://onsemi.com
Description
The NB6L72 is a 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 products.
