NBSG72A

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device  unctional operation is not implied, damage may occur and reliability may be affected.

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 NBSG72A is housed in a low profile 3 X 3 mm  16−pin QFN package. Differential inputs incorporate internal 50
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.
