Product Details


Fig. 1 Functional Block Diagram

The temperature stableASNT5117-KMC SiGe IC provides broadband data retiming functionality and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can sample a high-speed data signal dp/dn with a full-rate external clock cp/cn to create a full-rate retimed NRZ data output qp/qn. The internal DC common mode voltage levels on data inputs dp/dn can be adjusted by applying analog voltage to the control input dccd. The output amplitude of the DFF is adjustable by using the control voltage ampadj. 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.
