Fig. 1. Functional Block Diagram

The temperature stable ASNT6160B-KMM 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 3-pin control port gncrl0/1/2 with accuracy of 0.5dB as shown in Table 1.

11.0The active input selection is performed through the external high-speed single-ended port sel that can bereferenced to either vcc or vee depending on the state of the single-ended control signal lvlcrl.
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 should
be used.
For the best performance, the external 50Ohm terminations for the outputs should be connected to vcc,
but not to ground!
The part features an additional internal supply voltage vn1p3 that is also accessible through thecorresponding pin. This pin is recommended to be left not connected but can be also used for adjustmentof the output eye by applying an external voltage source within the range specified in ELECTRICAL
CHARACTERISTICS. The external supply should be able to both source and sink a current of about
1mA.
Different PCB layouts will be needed for each different power supply combination.

ABSOLUTE MAXIMUM RATINGS
Caution: Exceeding the absolute maximum ratings shown in Table 2 may cause damage to this productand/or lead to reduced reliability. Functional performance is specified over the recommended operating
conditions for power supply and temperature only. AC and DC device characteristics at or beyond theabsolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced toground (assumed vcc).

PACKAGE INFORMATIONThe chip die is housed in a custom 44-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.
The part’s identification label is ASNT6160B-KMM. The first 9 characters of the name before the dashidentify the bare die including general circuit family, fabrication technology, specific circuit type, and partversion while the 3 digits after the underscore represent the package’s manufacturer, type, and pin out
count.
This device complies with the Restriction of Hazardous Substances (RoHS) per EU 2002/95/EC for all six
substances.
