Analog Devices / Maxim Integrated MAX3521 Upstream Amplifiers
Analog Devices Inc MAX3521 Upstream Amplifiers are integrated CATV upstream amplifier ICs designed to exceed the Data Over Cable Service Interface Specification (DOCSIS) 3.0 requirements. These amplifiers operate at a 5MHz to 85MHz input frequency range and can simultaneously transmit four QPSK modulated carriers, each at +61dBmV, within this range. The Analog MAX3521 upstream amplifiers are available in a 20-pin TQFN package. These RF amplifiers operate over an extended industrial temperature range of -40°C to 85°C. Analog Devices Inc. MAX3521 Upstream Amplifiers applications include DOCSIS 3.0 plus cable modems and gateways, VOIP modems, and set-top boxes.
