cp cnFig. 1. Functional Block Diagram

The temperature stable ASNT5012-KMC SiGe IC provides broadband data retiming functionality, and isintended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can sample a highspeed data signal dp/dn with a full-rate external clock cp/cn to create a full-rate retimed NRZ data output
outp/outn.
The data input buffer is designed to have increased input signal sensitivity, and is able to operate over awider range of input common mode (CM) voltages. The part’s I/O’s support the CML logic interface withon chip 50Ohm termination to vcc, and may be used differentially, AC/DC coupled, single-ended, or inany 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 optimalperformance.

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.

ABSOLUTE MAXIMUM RATINGS
Caution: Exceeding the absolute maximum ratings shown in Table 1 may cause damage to this productand/or lead to reduced reliability. Functional performance is specified over the recommended operating
conditions for power supply and temperature only. AC and DC device characteristics at or beyond theabsolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced toground (assumed vcc).

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 ASNT5012-KMC. The first 8 characters of the name before theunderscore identify the bare die including general circuit family, fabrication technology, specific circuit
type, and part version while the 3 characters after the underscore 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 tensubstances.
