MT1230 IF VARIABLE-GAIN
AMPLIFIER
PRODUCT BRIEF
The MT1230 IF variable-gain
amplifier offers low distortion, low
noise, and low power consumption.
MT1230 IF Variable-Gain Amplifier
The Microtune MT1230 is a
low-cost intermediate frequency
(IF) variable-gain amplifier IC for
use in digital cable TV (CATV),
cable modem, internet protocol
(IP) telephony, cable-ready TV,
and digital TV systems.
The MT1230 provides both a
high impedance differential input
and a low impedance differential
output, making it immune to
common mode noise and
minimizing shielding
requirements. Operating from a
single +5V supply, the two-stage
amplifier design typically draws
20 mA. The temperature-
compensated analog control
voltage produces a dB linear gain
characteristic throughout the
entire control voltage range.
The MT1230 is available in an
8-pin TSSOP package.
