General Description
The TP3401 TP3402 and TP3403 are complete monolithic transceivers for data transmission on twisted pair subscriber loops They are built on National’s double poly microCMOS process and require only a single a 5 Volt supply Alternate Mark Inversion (AMI) line coding in which binary ‘1’s are alternately transmitted as a positive pulse then a negative pulse is used to ensure low error rates in the presence of noise with lower emi radiation than other codes such as Biphase (Manchester) Full-duplex transmission at 144 kb s is achieved on a single twisted wire pair using a burst-mode technique (Time Compression Multiplexed) Thus the devi
