Transceiver Block Architecture
Figure 1–29. Serializer Block in 8-Bit PCS-PMA Interface
Note to
(1) The CMU0 clock divider of the master transceiver block provides the clocks. It is used only in bonded modes (for example, Basic ×8, PCIe ×8 mode).
Figure 1–30. Serializer Bit Order
Note to
(1) It is assumed that the input data to the serializer is 8 bits (channel width = 8 bits or 16 bits with the 8B/10B encoder disabled).
