The temperature stable ASNT5050-PQC SiGe IC can be utilized as either a high isolation selector switch or a high speed 2:1 serializer, and is intended for use in high-speed measurement / test equipment. When employed as a selector switch, ASNT5050-PQC can route one of its differential input signals d0p/d0n or d1p/d1n to its differential output outp/outn while effectively blocking the other data input. Selection of a specific data input is achieved through appropriate external DC biasing of the selector signal inputs cp/cn. As a 2:1 serializer, the part can receive a high speed input data signal into d0p/d0n and effectively multiplex them into a double frequency rate NRZ output data signal to its differential output outp/outn by using a high speed input clock signal on its selector signal inputs. The part’s I/Os support the CML logic interface with on chip 50Ω termination to vcc and may be used differentially, AC/DC coupled, single-ended, or in any combination. It operates from a single +3.3V or -3.3V power supply.
