Fig. 1. Functional Block Diagram
The temperature stable ASNT5111-KMC SiGe IC provides broadband data retiming functionality and is
intended 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
qp/qn.
The part’s I/O’s support the CML logic interface with on chip 50Ohm termination to vcc and may be used
differentially, AC/DC coupled, single-ended, or in any 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 optimal performance.
POWER SUPPLY CONFIGURATION
The part can operate with either a negative supply (vcc = 0.0V = ground and vee = −4.0V), or a positive
supply (vcc = +4.0V 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 needed
for each different power supply combination.
All the characteristics detailed below assume vcc = 0.0V and vee = -4.0V.

ABSOLUTE MAXIMUM RATINGS
Caution: Exceeding the absolute maximum ratings shown in Table 1 may cause damage to this product
and/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 the
absolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced to
ground (assumed vcc).

PACKAGE INFORMATION
The 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 this
section to be soldered to the vcc plain, which is ground for a negative supply, or power for a positive
supply.
The part’s identification label is ASNT5111-KMC. The first 8 characters of the name before the dash
identify the bare die including general circuit family, fabrication technology, specific circuit type, and part
version 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.
