DESCRIPTION
The ARA1400S12 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
MCNS/DOCSIS Compliant Cable Modems
CATV Interactive Set-Top Box
Telephony over Cable Systems
a single polarity +5V supply. This
part is a single ended design
that does not require an output
balun to achieve 52 dBc 2
nd
harmonic performance at +60
dBmV output levels. Both the
input and output are matched to
75 ohms. The precision
attenuator provides up to 56 dB
of
attenuation
increments. The ARA1400S12
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.
