MT1550 UPSTREAM
AMPLIFIER
PRODUCT BRIEF
The MT1550 is a 3.3V programmable
gain upstream amplifier with integrated
anti-aliasing filter.
The MT1550 is a low-cost
programmable-gain power amplifier
IC for use in CATV upstream
applications. The Microtune
MT1550 is a 3.3 volt part optimized
for the DOCSIS 1.1 upstream
standard. The MT1550 also includes
an on-chip input anti-aliasing filter,
thereby reducing external system
costs.
The device’s specified frequency
range is from 5MHz to 65MHz, and
can output 67dBmV through a 1:1
impedance-ratio transformer. A 3-
wire digital serial bus controls the
variable gain, with gain control
available in 1dB steps and a
nominal 59dB gain range.
The MT1550 may be disabled via
an external control pin. The transmit-
disable mode not only minimizes
output noise by shutting off the
output stage, but also maintains its
output impedance at nominal levels.
Output transients are nominally less
than 16mVp-p at 61dBmV output
level during transmit enable/disable
switching.
Operating from a single +3.3V
supply, the amplifier’s typical
current draw at maximum gain, or
minimum attenuation, is 259mA.
Additional internal circuitry reduces
the amplifier’s power consumption
depending on gain setting.
Transmit-disable mode power
supply current is reduced to a
nominal of 62mA. A shutdown mode
further reduces current to a nominal
of 70
μ
A.
The MT1550 is available in a 20-
pin MicroLeadFrame package
with an exposed pad for the
extended industrial temperature
range of -40°C to +85°C.
