The temperature stable ASNT5024-KMC SiGe IC provides active broadband data/clock signal splitting,and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can deliver
three phase-matched copies of the broadband data/clock input signal cp/cn to three high-speed
differential outputs out0p/out0n, out1p/out1n, out2p/out2n.
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 negative supply (vcc = 0.0V = ground and vee = −3.3V), or 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.

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 ASNT5024-KMC. The first 8 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 out
count.

This device complies with the Restriction of Hazardous Substances (RoHS) per 2011/65/EU for all ten
substances.
