Product Details

Fig. 1 Functional Block Diagram

The temperature stable ASNT6193-KHC 1-to-3 analog signal splitter is intended for use in high-speed interleaved ADCs or similar systems. The IC shown in Fig. 1 can receive a broad-band analog signal at its differential input dp/dn and effectively distribute it to three separate phase matched differential outputs q1p/q1n, q2p/q2n, and q3p/q3n with a nominal gain of 0dB. A low-speed analog current control ief2c is available for bandwidth and peaking adjustment. A flat frequency response can be achieved at lower control voltages.

The part’s I/O’s support the CML logic interface with on chip 50Ohm termination to vcc and may be used differentially, AC/DC coupled, single-ended, or in any combination (also see POWER SUPPLY CONFIGURATION). In the DC-coupling mode, the input signal’s common mode voltage should comply with the specifications shown in ELECTRICAL CHARACTERISTICS. In the AC-coupling mode, the input termination provides the required common mode voltage automatically. Optimal performance is achieved with differential DC signaling mode.
