Notes to
(1) The transmitter is in bit-slip mode.
(2) This block is optional in this mode.
(3) The RX phase compensation FIFO is automatically set in register mode. However, you have the option to set the TX phase compensation FIFO in
(4) Typically, the 8B/10B encoder and decoder are used when you use deterministic latency to implement CPRI or OBSAI protocols. However, you

Figure 1–55
IEEE 802.3 defines the 1000 Base-X PHY as an intermediate, or transition, layer that
interfaces various physical media with the media access control (MAC) in a GIGE
system. It shields the MAC layer from the specific nature of the underlying medium.
The 1000 Base-X PHY, which has a physical interface data rate of 1.25 Gbps, is divided
into three sublayers—the physical coding sublayer (PCS), physical media attachment
(PMA), and physical medium dependent (PMD). These sublayers interface with the
MAC through the gigabit medium independent interface (GMII).
