The device is operated with a single supply voltage of 5V while the attached TX-driver stage is generating a 7Vpp (AS5501) or a 14Vpp (AS5502) FSK-signal with very low distortion which needs a supply of the external driver stage of 12V (AS5501) and 24V (AS5502) respectively. The high output-voltages which gets coupled to the power-line by using a transformer with proper ratios gives the advantage to lower the output impedance of the buffer while the buffer supply-current gets kept small. Precise filtering gives an receiver performance with low BER-figures at <13dB of S/N white inband-noise and <-40dB S/N with monochromatic outband-noise and a sensitivity of 1.5mV The carrier frequency is programmable in a range from 64kHz to 140kHz to support a big variety of communication-bands including home-automation applications. Modulation depth and Baud-Rate are programmable to 600Hz/1200Hz and 600, 1200, 2400B/s. There is a carrier-detect function included to support channels with protocoll. In addition to the modem-function a reference voltage output is available as well as a supply-supervision. Rev A, May 2000 Page 1/25 AS5501 / AS5502 Multimode Powerline Modem Data Sheet T...
