The IC shown in Fig. 1 receives a data signal with the rate of up to 5.6Gbps through differential port inp/inn
and a clock signal with the frequency of up to 5.6GHz through differential port cp/cn. The signals are used by
the Register to generate 9 copies of the input data signal shifted by ½ of the clock period. Those 9 copies arelinearly summed in the Adder with different weights and polarities that are externally controlled through theTap Control’s input single-ended ports t1/t2/t3/t4/t5/t6/t7/t8/t9. The resulting signal with the required digitalpre-emphasis is supplied to the differential output (outp/outn) through a linear output buffer.
The input and output signals of the register are presented in Fig. 2.

Fig. 2. Register Timing Diagram, 5.6GHz Clock.

The weight and polarity of each tap are set by the voltage on the corresponding input control port t1-t9. The
dependence of the tap’s current value and polarity on the input control voltage are presented in Fig. 3 and Fig.
4. The voltages below the threshold (approximately vcc-0.6V) correspond to negative currents while thevoltages above the threshold correspond to positive currents.

To achieve the required output signal amplitude of M[%] of the maximum value independent from the tap
control settings, the value of curadj should be set in accordance with the equation:
100  M [%]curadj[%]  i 9.
t[%]i1 iAs can be seen from the graphs above, all controls cover a range from 0% to about 130% in order to ensure thelinear control characteristics within the operational region.
The part’s output buffers support the CML-type interface with on chip 50Ohm termination to vcc and may be
used in either DC or AC coupling modes (see also POWER SUPPLY CONFIGURATION). The differential DC
signaling is recommended for the optimal performance.
The part’s input buffer supports the CML-type interface with equivalent on-chip 50Ohm termination and can beused in either DC or AC coupling modes. In the first mode, the input signal’s common mode voltage should
comply with the specifications shown in ELECTRICAL CHARACTERISTICS. In the second mode, the input
termination provides the required common mode voltage automatically. The differential signaling is
recommended for the optimal performance.

POWER SUPPLY CONFIGURATION
IC can operate with either negative supply (vcc = 0.0V=ground and vee = -3.3V), or positive supply (vcc =+3.3V and vee = 0.0V=ground). In case of the positive supply, all I/Os need AC termination when connected toany 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. 6. The package provides a center heatslug located on its back side to be used for heat dissipation. ADSANTEC recommends for this section to besoldered to the vcc plain, which is ground for a negative supply, or power for a positive supply.
The package’s leads will be trimmed to a length of 1.0mm. After trimming, the package’s leads will be further
processed as follows:
1. The lead’s gold plating will be removed per the following sections of J-STD-001D:
3.9.1 Solderability
3.2.2 Solder Purity Maintenance3.9.2 Solderability Maintenance3.9.3 Gold Removal
2. The leads will be tinned with Sn63Pb37 solder.
The part’s identification label is ASNT8170-KMM. 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 whilethe 3 digits after the underscore represent the package’s manufacturer, type, and pin out count.
This device complies with the Restriction of Hazardous Substances (RoHS) per EU 2002/95/EC for all six
substances.
