| Pin Name | Direction | Description |
|---|---|---|
| VCCINT_GT | N/A | Digital supply voltage for select modules in the GTM transceivers |
| GTY_RXP, GTY_RXN, GTYP_RXP, GTYP_RXN, GTM_RXP, GTM_RXN | Input | RXP and RXN are the differential input pairs for each of the receivers in the transceiver Quad |
| GTY_TXP, GTY_TXN, GTYP_TXP, GTYP_TXN, GTM_TXP, GTM_TXN | Output | TXP and TXN are the differential output pairs for each of the transmitters in the transceiver Quad |
| GTY_REFCLKP, GTY_REFCLKN, GTYP_REFCLKP, GTYP_REFCLKN, GTM_REFCLKP, GTM_REFCLKN | Input | Configured as either reference clock input pins or as RX recovered clock output pins for the transceiver Quad |
| GTY_AVTTRCAL, GTYP_AVTTRCAL, GTM_AVTTRCAL | N/A | Bias current supply for the termination resistor calibration circuit |
| GTY_RREF, GTYP_RREF, GTM_RREF | N/A | Calibration resistor input pin for the termination resistor calibration circuit |
| GTY_AVCC, GTYP_AVCC, GTM_AVCC | N/A | The analog supply for the internal analog
circuits of the transceiver Quad tiles. This includes the analog
circuits for the PLLs, transmitters, and receivers. Most packages
have multiple groups of power supply connections in the package for
the AVCC. Refer to the package pin definitions to identify in which power supply group a specific transceiver Quad is located. |
| GTY_AVTT, GTYP_AVTT, GTM_AVTT | N/A | AVTT is the analog supply for the transmitter and
receiver termination circuits of the transceiver Quad tile. Most
packages have multiple groups of power supply connections in the
package for AVTT. Refer to the package pin definitions to identify in which power supply group a specific transceiver Quad is located. |
|
GTY_AVCCAUX GTYP_AVCCAUX GTM_AVCCAUX |
N/A | AVCCAUX is the analog LCPLL voltage supply for
the transceivers. Most packages have multiple groups of power supply
connections in the package for AVCCAUX. Refer to the package pin definitions to identify in which power supply group a specific transceiver Quad is located. |
