Fig. 1. Functional Block Diagram

The temperature stable and broadband ASNT5051-PQC SiGe IC can be utilized as a high isolation
selector switch and is intended for use in high-speed measurement / test equipment. When The IC shownin Fig. 1 can route one of its differential data input signals (d0p/d0n or d1p/d1n) to its differential output(outp/outn) while effectively blocking the other data input with high isolation. Selection of a specificdata input is achieved through appropriate external DC biasing of the selector signal inputs (cp/cn). It isalso possible to apply an up to 1GHz AC signal to the selector signal inputs.
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 (see also 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.

POWER SUPPLY CONFIGURATION
The part can operate with either a negative supply (vcc = 0.0V = ground and vee = −3.3V), or a positivesupply (vcc = +3.3V and vee = 0.0V = ground). In case of the positive supply, all I/Os need ACtermination 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 and vee = -3.3V.
