The temperature stable ASNT5190B-KMC SiGe IC can be utilized as a high speed 1:2 demultiplexer, andis intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can receive ahigh 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 signalcp/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 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 a positive supply, all I/Os need AC termination
when connected to any devices with 50Ohm termination to ground. Different PCB layouts will be neededfor each different power supply combination.

All the characteristics detailed below assume vcc = 0.0V and vee = -3.3V.

TYP

PACKAGE INFORMATIONThe chip die is housed in a custom 24-pin CQFP 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 positivesupply.
The part’s identification label is ASNT5190B-KMC. 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 characters after the dash represent the package’s manufacturer, type, and pin outcount.
This device complies with the Restriction of Hazardous Substances (RoHS) per 2011/65/EU for all tensubstances.
