Functional Block Diagram The temperature stable and broadband ASNT5051-KMC 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 shown in 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 specific data input is achieved through appropriate external DC biasing of the selector signal inputs (cp/cn). It is also 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 used differentially, AC/DC coupled, single-ended, or in any combination (see also 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. POWER SUPPLY CONFIGURATION The part can operate with either a negative supply (vcc = 0.0V = ground and vee = −3.3V), or a positive supply (vcc = +3.3V 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 and vee = -3.3V.

The package provides a center heat slug located on its back side to be used for heat dissipation. ADSANTEC recommends for this section to be soldered to the vcc plain, which is ground for a negative supply, or power for a positive supply. The part’s identification label is ASNT5051-KMC. The first 8 characters of the name before the dash identify the bare die including general circuit family, fabrication technology, specific circuit type, and part version while the 3 characters after the dash represent the package’s manufacturer, type, and pin out count. This device complies with the Restriction of Hazardous Substances (RoHS) per 2011/65/EU for all ten substances.
