Product Details

Fig. 1. Functional Block Diagram

ASNT5073A-PQC is a wide-band clock variable delay line fabricated in SiGe technology. The IC shown in Fig. 1 provides an adjustable delay of its differential output signal outp/outn in relation to its input signal ip/in. The delay adjustment range is temperature-stabilized. The delay is controlled through a wide-band differential tuning port icntp/icntn.

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 of 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.
