DESCRIPTION

Fig. 1 Functional Block Diagram

The temperature stable ASNT5113-KMC SiGe IC provides broadband data retiming functionality and is intended for use in high-speed measurement / test equipment. The ASNT5113-KMC 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 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 actual common mode voltage levels at data inputs dp/dn can be adjusted by applying voltages between vee and vcc to the corresponding control inputs dcinp/dcinn.

 

The part’s I/Os support the CML-type 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 specifications shown in the electrical characteristics table within the part's datasheet. In the AC-coupling mode, the input termination provides the required common mode voltage automatically. It should be noted that the control inputs dcinp/dcinn should always be connected to voltage sources to ensure correct 50Ω terminations for the data inputs, and the differential DC signaling mode is recommended for optimal performance.
