Table 1. GTY Transceiver Quad Pin Definitions.
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.
