DESCRIPTION

 

The temperature stable ASNT6160A-KMC analog signal selector 1-of-2 is intended for use in high-speed systems. The IC shown in Fig. 1 can deliver one of two different broad-band analog differential signals d0p/d0n and d1p/d1n to its differential output qp/qn with a nominal gain of 0dB. The gain can be fine-tuned using the 2-pin control port gncrl1/2 with accuracy of 0.5dB as shown in Table 1.

The active input selection is performed through the external high-speed single-ended port sel that can be referenced to either vcc or vee depending on the state of the single-ended control signal lvlcrl.

 

The part’s I/Os support CML-type differential interface with on-chip 50Ohmtermination to vcc, and may be used differentially, AC/DC coupled, single-ended, or in any combination (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. The differential DC signaling mode is recommended for optimal performance. In particular, the specified output common-mode voltage level is guaranteed only in case of external single-ended 50Ohm DC termination to vcc.
