Fig. 1 Functional Block Diagram
The temperature stable ASNT5160-KMC SiGe IC provides broadband AND/OR Boolean logic functionality, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can AND/OR a high-speed data input signal dap/dan with another high-speed data input signal dbp/dbn, and deliver a high-speed NRZ data output signal qp/qn. An RZ data output signal can be generated by inserting up to half of the IC’s maximum data input frequency into one data input signal dap/dan or dbp/dbn while providing an up to its maximum clock signal analog bandwidth into the other data input dap/dan or dbp/dbn.
The part’s I/O’s 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.
