Product Details


Fig. 1 Functional Block Diagram

The temperature stable ASNT5111-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 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. In the DC-coupling mode, the input signal’s common mode voltage should comply with the specifications shown in the electrical characteristics section within the part’s datasheet. In the AC-coupling mode, the input termination provides the required common mode voltage automatically. The differential DC signaling mode is recommended for optimal performance, and it operates from a single +4.0V or -4.0V power supply.
