The temperature stable ASNT5023-KMM 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
four phase-matched copies of the broadband data/clock input signal cp/cn to four high-speed differential
outputs q1p/q1n, q2p/q2n, q3p/q3n, q4p/q4n.
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 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.

PACKAGE INFORMATIONThe chip die is housed in a custom 44-pin CQFP package shown in Fig. 2. Even though the package
provides a center heat slug located on the back side of the package to be used for heat dissipation,
ADSANTEC does NOT recommend for this section to be soldered to the board. If the customer wishes
to solder it, it should be connected to the vcc plain that is ground for the negative supply or power for thepositive supply.
The part’s identification label is ASNT5023-KMM. 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 outcount.
The IC complies with the Restriction of Hazardous Substances (RoHS) per EU 2002/95/EC for all 6substances.
