DESCRIPTION

 

Fig. 1 Functional Block Diagram

The temperature stable ASNT5020-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 two phase-matched copies of the broadband data/clock input signal cp/cn to two high-speed differential outputs out0p/out0n, out1p/out1n.

 

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.
