The temperature stable ASNT6160A-KMC analog signal selector 1-of-2 is intended for use in high-speedsystems. 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 finetuned using the 2-pin control port gncrl1/2 with accuracy of 0.5dB as shown in Table 1.

gncrl2 gncrl1 Gain, dB Comments

111.0The active input selection is performed through the external high-speed single-ended port sel that isreferenced to vcc.
The part’s I/Os support the CML-type interface with on chip 50Ohm termination to vcc, and may be useddifferentially, AC/DC coupled, single-ended, or in any combination (also see POWER SUPPLYCONFIGURATION). 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, theinput termination provides the required common mode voltage automatically. The differential DC
signaling mode is recommended for optimal performance. In particular, the specified output commonmode voltage level is guaranteed only in case of external single-ended 50Ohm DC termination to vcc.

POWER SUPPLY CONFIGURATION
The part can operate with either a negative supply (vcc = 0.0V = ground), or a positive supply (vee =0.0V = ground). In case of a positive supply, all I/Os need AC termination when connected to any devices
with 50Ohm termination to ground. In any case, the input common mode voltage level is shifted downfrom vcc by a certain voltage of ΔVICM as specified in ELECTRICAL CHARACTERISTICS. To have theinput common mode voltage equal to ground, a floating negative supply scheme detailed in Fig. 2 shouldbe used.
For the best performance, the external 50Ohm terminations for the outputs should be connected to vcc,
but not to ground!
Different PCB layouts will be needed for each different power supply combination.

PACKAGE INFORMATIONThe chip die is housed in a custom 24-pin CQFP package shown in Fig. 3. The package provides a center
heat slug located on its back side to be used for heat dissipation. ADSANTEC recommends for thissection to be soldered to the vcc plain, which is ground for a negative supply, or power for a positivesupply.
