Methods and apparatus for a common denominator transceiver design for data transmission

摘要

A transceiver for exchanging data with a transmission channel using any of the 100BaseT2, 100BaseTX, or 100BaseT4 standards, which includes a receive circuit for receiving analog data from the transmission channel. The receive circuit includes a first switch and a first analog-to-digital converter coupled to the first switch. The receive circuit further includes a second analog-to-digital converter coupled to the first switch. There is further included a second switch coupled to the first analog-to- digital converter and to the second analog-to-digital converter. The analog data is switched by the first switch into the first analog-to- digital converter and the second analog- to-digital converter to allow the first analog-to-digital converter and the second analog-to-digital converter to support sampling requirements of any of the 100BaseT2, the 100BaseTX, or the 100BaseT4 standards.
