Fig. 1 Functional Block Diagram

The temperature stable ASNT5112-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 the high-speed data signal dp/dn with the full-rate external clock cp/cn to create the full-rate retimed NRZ data output qp/qn. The data input buffer is designed to have increased input signal sensitivity and is able to operate over a wider range of input common mode (CM) voltages. 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 +3.3V or -3.3V power supply.
