| Pin Name | Direction | Description |
|---|---|---|
| GTY_RXP, GTY_RXN | Input | GTY_RXP and GTY_RXN are the differential input pairs for each of the receivers in the GTY transceiver Quad |
| GTY_TXP, GTY_TXN | Output | GTY_TXP and GTY_TXN are the differential output pairs for each of the transmitters in the GTY transceiver Quad |
| GTY_REFCLKP, GTY_REFCLKN | Input | Configured as either reference clock input pins or as RX recovered clock output pins for the GTY transceiver Quad |
| GTY_AVTTRCAL | Input (Pad) | Bias current supply for the termination resistor calibration circuit |
| GTY_RREF | Input (Pad) | Calibration resistor input pin for the termination resistor calibration circuit |
| GTY_AVCC | Input (Pad) |
GTY_AVCC is the analog supply for the internal analog circuits of
the GTY transceiver Quad tile. This includes the analog circuits for
the PLLs, transmitters, and receivers. Most packages have multiple
groups of power supply connections in the package for GTY_AVCC.
Refer to the package pin definitions to identify in which power supply group a specific GTY transceiver Quad is located. The nominal voltage is 0.88VDC. |
| GTY_AVTT | Input (Pad) |
GTY_AVTT is the analog supply for the transmitter and receiver
termination circuits of the GTY transceiver Quad tile. Most packages
have multiple groups of power supply connections in the package for
GTY_AVTT.
Refer to the package pin definitions to identify in which power supply group a specific GTY transceiver Quad is located. The nominal voltage is 1.2VDC. |
| GTY_AVCCAUX | Input (Pad) |
GTY_VCCAUX is the
analog LCPLL voltage supply for the transceivers. Most packages have
multiple groups of power supply connections in the package for
GTY_AVCCAUX.
Refer to the package pin definitions to identify in which power supply group a specific GTY transceiver Quad is located. The nominal voltage is 1.8VDC. |
