Fig. 1. Functional Block Diagram

The temperature-stable linear amplifier IC shown in Fig. 1 has been fabricated in SiGe technology andprovides low-jitter broadband variable signal amplification between its input inp/inn and output
outp/outn signal ports. This IC is intended for use in high-speed communication systems. The gain
adjustment is performed through two independent external control ports vgc1 and vgc2. The typical gain
control characteristic is shown in Fig. 2.

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.
The on-chip peak detector delivers a single-ended output voltage pkdet reverse-proportional to the input

Additional control ports dcinp and dcinn can be used for input signal common-mode voltage adjustment.
For the optional output common-mode voltage adjustment, the output termination resistors are connected
to a separate positive supply voltage vcco that may be different from vcc.

POWER SUPPLY CONFIGURATION
The part can operate with either a negative supply (vcc = 0.0V=ground and vee = -3.3V), or a positivesupply (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.

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