Abstract
An apparatus for operating a low data-rate (LDR) link and legacy switch at a high data-rate (HDR) includes a first block and a second block. The first block receives input signals from the legacy switch and generates identical output signals. The second block receives the identical output signals and generates an HDR signal for communication over the LDR link coupled to an access point. Further, a media access control (MAC) interface communicates data at a first data rate with an Ethernet PHY block including a first-in-first-out (FIFO) module and a buffer. The FIFO receives data from the MAC interface at the first data rate and transmits data at a second data rate. The buffer receives data from the Ethernet port at the second data rate and transmits the received data at the first data rate in response to detection of an end of packet.
