Fig. 1. Functional Block Diagram
The temperature stable ASNT5117-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 internal DC common mode voltage levels on data inputs dp/dn can be adjusted by applying
analog voltage to the control input dccd. The output amplitude of the DFF is adjustable by using the
control voltage ampadj.
The part’s I/O’s support the CML logic interface with on chip equivalent 50Ohm termination and may be
used differentially, AC/DC coupled, single-ended, or in any combination (see also POWER SUPPLY
CONFIGURATION).
HS Clock Input Buffer
The buffer can accept high-speed signals at its differential CML input port cp/cn. It can also accept a
single-ended signal with a threshold voltage applied to the unused pin. It can handle a wide range of input
signal amplitudes. The buffer utilizes on-chip single-ended 50Ohm termination to vcc for each input line.
HS Data Input Buffer
The buffer can accept high-speed signals at its differential CML input port dp/dn. It can also accept a
single-ended signal with a threshold voltage applied to the unused pin. It can handle a wide range of input
signal amplitudes. The buffer utilizes on-chip single-ended 50Ohm termination to vcc for each input line.
The buffer allows for adjustment of its input DC common-mode voltage by changing the control voltage
dccd following the diagram shown in Fig. 2. Here the x-axis presents the dccd values, the y-axis presents
the common-mode voltage values, the red lines correspond to the dp input, the blue lines correspond to

the dn input, and the solid lines represent typical conditions while dotted and dashed lines represent slow
and fast conditions respectively.

HS Data Output Buffer
The buffer receives high-speed serial data from the DFF core and converts it into a differential CML
output signal qp/qn. Each buffer utilizes internal single-ended 50Ohm loads to vcc and requires singleended 50Ohm external termination. The termination resistors can be connected from each output directly
to vcc, or through DC blocks to vee. The amplitude of the output signals can be adjusted from 0V to its
maximum value using the external control voltage ampadj.
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 needed
for 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 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. 3. 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 ASNT5117-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.
