DESCRIPTION

Fig.1 Functional Block Diagram

The temperature stable ASNT5023-PQC SiGe IC provides active broadband data/clock signal splitting and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can deliver four phase-matched copies of the broadband data/clock input signal cp/cn to four high-speed differential outputs q1p/q1n, q2p/q2n, q3p/q3n, q4p/q4n.

 

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.
