Product Overview NBSG72A: 2 x 2 Crosspoint Switch, SiGe Differential, 2.5 V / 3.3 V, with Ouput Level Select For complete documentation, see the data sheet Product Description 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 Ω 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 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.
