Fig.1 Functional Block Diagram
The temperature stable ASNT5090-KMC SiGe IC can be utilized as a high speed 1:2 demultiplexer, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can receive a high speed differential data input signal dp/dn and effectively demultiplex it into two high speed differential data output signals q0p/q0n and q1p/q1n by using a high speed differential clock input signal cp/cn.
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 p
