Functional Block Diagram The temperature stable ASNT5190B-KMC SiGe IC can be utilized as a high speed 1:2 demultiplexer, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can receive a high speed differential data input signal dp/dn and effectively demultiplex it into two high speed differential data output signals q1p/q1n and q2p/q2n by using a high speed differential clock input signal cp/cn. The duty cycle of the internal clock can be adjusted through ports dcinp/dcinn. 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 a 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 ASNT5190B-KMC. The first 9 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.
