NBSG72A
2.5V/3.3V SiGe Differential
2 X 2 Crosspoint Switch
with Output Level Select
The NBSG72A is a high−bandwidth fully differential 2 X 2
crosspoint switch with Output Level Select (OLS) capabilities. This is
a part of the GigaComm™ family of high performance Silicon
Germanium products. The device is housed in a low profile 3 X 3 mm
16−pin QFN package.
Differential inputs incorporate internal 50
W
termination resistors
and accept NECL (Negative ECL), PECL (Positive ECL),
LVCMOS/LVTTL, CML, or LVDS. The OLS input is used to
program the peak−to−peak output amplitude between 0 mV and
800 mV in five discrete steps. The SELECT inputs are single−ended
and can be driven with either LVECL or LVCMOS/LVTTL
input levels.
