DESCRIPTION
The ARA2000S12 is a GaAs IC designed to perform the reverse path amplification and output level control
functions in a CATV Set-Top Box or Cable Modem. It incorporates a digitally controlled precision step
attenuator that is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output driver
amplifier. It is capable of meeting the MCNS/DOCSIS harmonic distortion specifications while only requiring
a single polarity +5V supply. This
part is a balanced design that
meets or exceeds the MCNS/
DOCSIS
requirement
for
harmonic
performance
@ +60dBmV output levels. Both
the input and output are matched
to 75 ohms. The precision
attenuator provides up to 56 dB
of
attenuation
in
1
dB
increments. The ARA2000S12 is
supplied in a 28-pin SSOP
package featuring a thermal heat
slug on the bottom of package.
Soldering this heat slug to the
ground plane of the PC board
ensures the lowest possible
thermal resistance for the device
resulting in a long MTF.
