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) signals in passive optical networks (PON). A gain-control input supports AGC operation with optical inputs having -6dBm to +2dBm average power. With 62dBΩ maximum 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.
Applications
- FTTH Optical Network Termination (ONT)

Product Detail
The MAX3654 evaluation kit (EV kit) is a factory-assembled printed circuit board (PCB) that provides two circuit versions—optical input and electrical input.
The optical circuit includes the photodiode bias circuitry, an op amp for feed-forward AGC operation, and a balun for single-ended 75Ω output. Through-hole pads are provided to attach a triplexer analog photodiode. It is important to select a photodiode with capacitance and inductance in the anode and cathode connections as symmetric as possible for optimum linearity.
The electrical circuit is normally configured with a 50Ω input for use with conventional test and measurement equipment and a 75Ω output. The 75Ω output can be connected to 50Ω test and measurement equipment using a minimum loss pad. If desired, the MAX3654 input can also provide a 75Ω input by replacing R12 and R13 with 25Ω resistors.
Applications
- FTTH Optical Network Termination (ONT)
