single-chip 10/100m ethernet phyceiver
general description features
the sr8201g are single-chip/port 10/100mbps ethernet ? supports ieee 802.3az-2010 (eee)
phyceiver with rmii interface (reduced media ? 100base-tx ieee 802.3u compliant
independent interface). ? 10base-t ieee 802.3 compliant
? supports rmii mode
the sr8201g implement all 10/100m ethernet physical- ? full/half duplex operation
layer functions including the physical coding sublayer ? supports power down mode
(pcs), physical medium attachment (pma), twisted pair ? supports interrupt function
physical medium dependent sublayer (tp-pmd), ? automatic polarity correction
10base-tx encoder/decoder, and twisted-pair media ? provide two network status leds
