MAX3654：47MHz to 870MHz Analog CATV Transimpedance Amplifier

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.

Key Features 47MHz to 870MHz Operation -6dBm to +2dBm Optical Input Range 21dBm OIP3, 47dBm OIP2 5.5pA per root-Hz EIN (Amplifier Alone) 62dB Gain at 47MHz 18dB Transimpedance (Gain) Control Integrated +4dB Gain Tilt (with Typical Photodiode) +5V Single-Supply Operation 700mW Power Dissipation -40°C to +85°C Operating Temperature Range 4mm x 4mm TQFN Package
