Pins Dir Description

MGTREFCLK0P

MGTREFCLK0N

In/Out (Pad) Configured as either reference clock input pins or RX recovered clock output pins for the Quad.

MGTREFCLK1P

MGTREFCLK1N

In/Out (Pad) Configured as either reference clock input pins or RX recovered clock output pins for the Quad.

CH[0/1/2/3]_GTYRXP/CH[0/1/2/3]_GTYRXN

CH[0/1/2/3]_GTYPRXP/CH[0/1/2/3]_GTYPRXN

In (Pad) RXP and RXN are the differential input pairs for each of the receivers in the transceiver Quad.

CH[0/1/2/3]_GTYTXP/CH[0/1/2/3]_GTYTXN

CH[0/1/2/3]_GTYPTXP/CH[0/1/2/3]_GTYPTXN

Out (Pad) TXP and TXN are the differential output pairs for each of the transmitters in the transceiver Quad.
MGTAVTTRCAL In (Pad) Bias current supply for the termination resistor calibration circuit. See Termination Resistor Calibration Circuit.
MGTRREF In (Pad) Calibration resistor input pin for the termination resistor calibration circuit. See Termination Resistor Calibration Circuit.
GTY_AVCC In (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. For Versal adaptive SoCs, the nominal voltage is 0.88 VDC.

GTYP_AVCC In (Pad)

GTYP_AVCC is the analog supply for the internal analog circuits of the GTYP 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 GTYP_AVCC.

Refer to the package pin definitions to identify in which power supply group a specific GTYP transceiver Quad is located. For Versal adaptive SoCs, the nominal voltage is 0.92 VDC.

GTY_AVTT In (Pad)

GTY_AVTT is the analog supply for the transmitter and receiver termination circuits of the GTY and GTYP 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 or GTYP transceiver Quad is located. For Versal adaptive SoCs, the nominal voltage is 1.2 VDC.

GTY_AVCCAUX In (Pad)

GTY_AVCCAUX is the auxiliary 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. For Versal adaptive SoCs, the nominal voltage is 1.5 VDC.

Figure 1. Transceivers External Power Supply Connections

The preceding figure shows the external power supply connections with the GTY or GTYP transceivers. For GTYP_AVCC, the nominal voltage is 0.92 VDC.instead of 0.88 VDC.

Note: The voltage values are nominal. See the Versal device data sheets for values and tolerances.
