Fig. 1. Functional Block Diagram

The temperature stable ASNT5136-KMC SiGe IC provides low jitter broadband variable signal
amplification between its input and output signal ports and is intended for use in high-speed
communication systems. The circuit shown in Fig. 1 accepts an analog signal at its input differential port
inp/inn and delivers a voltage-limited output signal at the output differential port outp/outn. The
common-mode voltage levels of input signals can be adjusted using analog control inputs dcinp/dcinn.
The total gain can be externally adjusted through the gain control port vgc. The input amplitude can bemonitored using the analog output voltage pkdet.
The part’s I/Os 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.

POWER SUPPLY CONFIGURATIONThe part 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 whenconnected to any devices with 50Ohm termination to ground. Different PCB layouts will be needed foreach different power supply combination.

All the characteristics detailed below assume vcc = 0.0V and vee = -3.3V.

VPACKAGE INFORMATIONThe chip die is housed in a custom 24-pin CQFP package shown in Fig. 2. 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.
The part’s identification label is ASNT5136-KMC. The first 8 characters of the name before the dashidentify the bare die including general circuit family, fabrication technology, specific circuit type, and partversion while the 3 characters after the dash represent the package’s manufacturer, type, and pin outcount.
This device complies with the Restriction of Hazardous Substances (RoHS) per 2011/65/EU for all ten
substances.
