DESCRIPTION

Fig. 1 Functional Block Diagram

The temperature stable ASNT5040-KMC SiGe IC provides broadband Exclusive-OR (XOR) Boolean logic functionality, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can XOR a high-speed clock input signal dap/dan with another high-speed clock input signal dbp/dbn, and deliver a high-speed double frequency clock output signal qp/qn.

 

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.
