2.1. Transceiver Design Flow in the Native PHY IP Core
The E-tile Native PHY IP core supports the following usage modes:
- PMA Direct
- PMA Direct high data rate PAM4
- Gearbox 64/66
The PMA Direct usage mode is for PMA NRZ and PAM4 usage in the E-tile Native PHY IP core. The data is transferred directly between PMA interface and FPGA fabric through the EMIB. You can place a total of 24 PMA Direct channels in one E-tile. This mode is supported for both NRZ and PAM4 with the following PMA interface widths:
- 64 (Only in PMA Direct high data rate PAM4 mode)
The E-tile Native PHY IP core's integrated reset controller provides reset signals for the PMA Direct and PMA Direct high data rate PAM4 modes.
