Product Details

Fig. 1 Functional Block Diagram

The temperature stable ASNT5142-ALP SiGe IC provides broadband Exclusive-OR (XOR) Boolean logic functionality in combination with a 1-to-5 output signal splitter, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can perform XOR operation with a high-speed data or clock input signal d1p/d1n and another high-speed data or clock input signal d2p/d2n. The resulting high-speed double-rate or double-frequency output signal is splitted into 5 identical signals and delivered to the output ports q1p/q1n, q2p/q2n, q3p/q3n, q4p/q4n, monp/monn. Independently controllable peakings and delays with an adjustable maximum value are provided in each channel.

The part’s I/O’s 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. In this case, the output can be used in DC-coupling mode and its common mode voltage can be adjusted using floating power supplies as described in the POWER SUPPLY CONFIGURATION section of the datasheet.
