qn5050selFig. 1. Functional Block Diagram

The temperature stable ASNT6163-KHC 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. It can also be used as atwo-channel analog mixer/adder of signals d0p/d0n and d1p/d1n. Two low-speed analog current
controls Ief1c and Ief3c are available for bandwidth and peaking adjustments.
The active input selection is performed through the external high-speed single-ended port sel that can bereferenced to either vcc or vee. When the low-speed single-ended control port on2 is set to vcc, it
switches the circuit into mixer/adder mode with both inputs active at the same time.
The part’s I/O’s support the CML logic interface with on chip 50Ohm termination to vcc and may be useddifferentially, AC/DC coupled, single-ended, or in any combination (also see Error! Not a valid
bookmark self-reference.). In the DC-coupling mode, the input signal’s common mode voltage should
comply with the specifications shown in ELECTRICAL CHARACTERISTICS. In the AC-couplingmode, the input termination provides the required common mode voltage automatically.

POWER SUPPLY CONFIGURATION
The part can operate with either negative supply (vcc = 0.0V = ground and vee = −3.6V), or positive
supply (vcc = +3.6V and vee = 0.0V = ground). In case of the positive supply, all I/Os need AC
termination when connected to any devices with 50Ohm termination to ground.
Different PCB layouts will be needed for each different power supply combination.

All the characteristics detailed below assume vcc = 0.0V = ground.

PACKAGE INFORMATIONThe chip die is housed in a custom 24-pin CQFN package shown in Fig. 2. 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 positive
supply.
