ASNT5102-KMC is a clock variable delay line fabricated in SiGe technology. The IC shown in Fig. 1
provides an adjustable delay of its differential output signal outp/outn in relation to its input signal
inp/inn. The delay is controlled through a wide-band differential tuning port icntp/icntn.
The part’s I/O’s support the CML logic interface with on chip 50Ohm termination to vcc and may be useddifferentially, AC/DC coupled, single-ended, or in any combination (see also POWER SUPPLYCONFIGURATION). 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, theinput termination provides the required common mode voltage automatically. The differential DC
signaling mode is recommended for optimal performance.
Due to an extremely low jitter, the part is suitable for use in high-speed measurement / test equipment.

Delay Control PortThe delay is controlled through a wide-band differential tuning port icntp/icntn. The delay control
diagram is shown in Fig. 2.

POWER SUPPLY CONFIGURATIONThe ASNT5102-KMC can operate with either a negative supply (vcc = 0.0V=ground and vee = -3.3V), ora positive supply (vcc = +3.3V and vee = 0.0V=ground). In case of a positive supply, all I/Os need ACtermination 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 productand/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 theabsolute maximum ratings are not assumed or implied. All voltage limits are referenced to ground.

PACKAGE INFORMATIONThe 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 thissection to be soldered to the vcc plain, which is ground for a negative supply, or power for a positivesupply.
