Fig. 1 Functional Block Diagram
The ASNT6114-KMC is an Active Power Divider which operates from DC to 25GHz. The component shown in Fig. 1 can receive a broad-band analog signal at its differential input dp/dn and effectively distribute it to two separate phase matched differential outputs q1p/q1n, q2p/q2n with a nominal gain of 0dB.The ASNT6114-KMC is intended for use in high-speed interleaved ADCs or similar systems.
The active power divider’s I/Os support the CML logic interface with on chip 50Ω termination to positive power supply rail and may be used differentially, AC/DC coupled, single-ended, or in any combination. In the DC-coupling mode, the input signal should have a specific common mode voltage. In the AC-coupling mode, the input termination provides the required common mode voltage automatically. Optimal performance is achieved with differential DC signaling mode.
