Fig. 1. Functional Block Diagram

The temperature stable ASNT8132-KMC SiGe IC provides broadband clock divide-by-2 functionality,
and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can process ahigh-speed clock input signal cp/cn and deliver a high-speed clock output signal qp/qn with 50% dutycycle.
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 complywith 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 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 neededfor each different power supply combination.

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

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 ASNT8132-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 outcount.
The IC complies with the Restriction of Hazardous Substances (RoHS) per EU 2002/95/EC for all 6substances.
