Fig. 1 Functional Block Diagram

The temperature stableASNT5121B-KHC SiGe IC provides active broadband clock signal splitting, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can process a broadband high-speed clock input signal cp/cn and deliver three broadband high-speed clock phase matched output signals c0p/c0n, c1p/c1n, c2p/c2n. 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.
