Datasheet	AS2507_austriamicrosystemsAG.pdf

The AS2507 is a CMOS integrated circuit that contains all the functions needed to build a 2wire inter network.

The device incorporates 2/4-wire conversion (hybrid), soft clipping for high speech quality, FSK mode

Line/speech circuit and signalling on one 14 pin CMOS chip Only 2 wires needed for power supply, signalling and speech Soft clipping to avoid harsh distortion Fully integrated 2/4 wire conversion Side tone cancellation Low noise Signalling with FSK modem Low standby power consumption allows parallel operation of up to 25 terminals on a bus pair with central supply Parallel operation of up to 70 terminals if supplied locally Controllable via simple µC interface Very few exte.
