The MAX3654 analog transimpedance amplifier (TIA) is
designed for CATV applications in fiber-to-the-home
(FTTH) networks. This high-linearity amplifier is intended
for 47MHz to 870MHz subcarrier multiplexed (SCM) sig-
nals in passive optical networks (PON). A gain-control
input supports AGC operation with optical inputs hav-
ing -6dBm to +2dBm average power. With 62dBΩ max-
imum gain at 47MHz and 18dB gain control range, the
minimum RF output level is 14dBmV/channel at -6dBm
optical input. A compact 4mm x 4mm package
includes all of the active RF circuitry required to convert
analog PIN photocurrent to a 75Ω CATV output.
This 700mW SiGe RF IC provides a low-cost, low-power
integrated analog CATV receiver solution for FTTH ONTs.
