| Option | I/O | Description |
| TXPCSRESET | Input | Active-High reset signal for the transmitter physical coding sublayer (PCS) logic. |
| TXBUFSTATUS | Output | 2-bit signal monitors the status of the TX elastic buffer. This option is not available when the TX buffer is bypassed. |
| TXRATE | Input | Transmit rate change port. |
| RXPCSRESET | Input | Active-High reset signal for the receiver PCS logic. |
| RXBUFSTATUS | Output | Indicates condition of the RX elastic buffer. Option is not available when the RX buffer is bypassed. |
| RXBUFRESET | Input | Active-High reset signal for the RX elastic buffer logic. This option is not available when the RX buffer is bypassed. |
| RXRATE | Input | Receive rate change port. |
| QPLLPD | Input | Visible only when GTX or GTH transceiver is selected. Powerdown port for QPLL. |
| CPLLPD | Input | Visible only when GTX or GTH transceiver is selected. Powerdown port for channel PLL (CPLL). |
