| 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 GigaCommTM 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.
