The temperature-stable linear amplifier ASNT6142-BD, which is fabricated in an advanced SiGetechnology, provides low-jitter broadband variable signal amplification between its input inp/inn andoutput outp/outn signal ports and is intended for use in high-speed communication systems. Gain
adjustment is performed through the external control port vgc. A graph of the amplifier’s single-ended
gain vs. vgc (where vcc=0V and x-axis values are settings below vcc) at 1.0GHz is shown below.
Differential gain is found by adding 6dB to these y-axis numbers.

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 proportional to the input signal’s
amplitude. Additional control ports dcinp and dcinn can be used for input signal common-mode voltage
adjustment. For optional output common-mode voltage adjustment, the output termination resistors areconnected to a separate positive supply voltage vcco.

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 ACtermination 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.

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.
