ASNT5001-PQC is a clock / data variable delay line fabricated in SiGe technology. The IC shown in Fig. 1
provides an adjustable delay of a broadband signal applied to its input port (“inp/inn”), with a temperaturestabilized adjustment range. Due to an extremely low jitter, the part is suitable for use in high-speed
measurement / test equipment. The part’s I/Os 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. The delay iscontrolled through a wide-band differential tuning port (“icntp/icntn”). The delay control diagram is shown inFig. 2. The output buffer is linearized for reduction of undershoots and overshoots on the output waveforms.

POWER SUPPLY CONFIGURATIONThe ASNT5001-PQC can operate with either a negative supply (“vcc” = 0.0V=ground and “vee” = -3.3V), or apositive supply (“vcc” = +3.3V and “vee” = 0.0V=ground). In case of the positive supply, all I/Os need ACtermination when connected to any devices with 50Ohm termination to ground. Different PCB layouts will beneeded 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/orlead 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 INFORMATIONThe chip die is housed in a standard 24-pin QFN package shown in Fig. 3. It is recommended that the center
heat slug located on the back side of the package is soldered to ground to help dissipate heat generated by thechip during operation.
The part’s identification label is ASNT5001-PQC. The first 8 digits of the name before the underscore 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.
