Fig. 1. Functional Block Diagram

The temperature stable ASNT5136-BD 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 and output signals can be adjusted using analog control inputs
dcinp/dcinn and dcoutp/dcoutn respectively. The total gain can be externally adjusted through the gain
control port vgc. The output signal’s peaking can be controlled through the port pkadj. The input
amplitude can be monitored using 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 ASNT5136-BD 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 AC
termination when connected to any devices with 50Ohm termination to ground. Different PCB layouts
will be needed for each different power supply combination.
The chip substrate should be connected to vee or completely isolated. DO NOT connect substrate to vcc!

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