Analog Front-End IC for Power Line Communication

Download Datasheet

  • Description

    The NJM45001 is an integrated, Powerline communications(PLC) analog front-end (AFE) device that is capable of capacitive- or transformer-coupled connecttions to the powerline while under the control of a Renesas Electronics Corporation Modem IC (e.g.uPD809508K8). The integrated driver is able to drive low-impedance line that require up to 3.0A (typical) into reactive road. The integrated receiver is able to select gain that is -18dB, -6dB, 0dB and +12dB. The NJM45001 operates from a single power supply in the range of 8V to 22V. At maximum output current, a wide range output swing provides an 11-Vpp capability with a nominal 15V supply. The NJM45001 is internally protected against overtemperature conditions. It also provides an adjustable current limit. An interrupt output is provided that indicates thermal limit. There is also shutdown pin that can be used to quickly put the device into its lowest power state. The NJM45001 is housed in a thermally-enhanced, surface-mount exposure-Pad package (HTSSOP24) Operation is specified over the junction temperature of -40°C to +150°C.
