Functional Block Diagram The temperature stable ASNT5114-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 data input buffer is designed to have increased input signal sensitivity and is able to operate over a wider range of input common mode (CM) voltages. The actual common mode voltage levels on data inputs dp/dn can be adjusted by applying voltages between vee and vcc to the corresponding control inputs dcinp/dcinn. 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). In case of AC-coupled input data signals, the internal common mode voltage levels at the inputs of the input buffer are defined by on-chip resistive dividers. It should be noted that the control inputs dcinp/dcinn should be always connected to voltage sources to ensure correct 50Ohm terminations for the data inputs. 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.

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 ASNT5114-KMC. The first 8 characters of the name before the underscore 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 ten substances.
