1.3.2. GTS Transceiver Pins

Note: Altera recommends that you create an Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software will check your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
Table 17.  GTS Transceiver Pins
Pin Name Pin Functions Pin Description Connection Guidelines
RCOMP_GTS[L1,R4][A,B,C,D]_P Input External biasing resistor for GTS.

Connect each RCOMP_GTS[L1,R4][A,B,C,D]_P pin with a 499-Ω resistor (± 0.1%) to the RCOMP_GTS[L1,R4][A,B,C,D]_N pin.

In the PCB layout, the trace from this pin to the resistor needs to be routed such that it avoids any aggressor signals.

Leave these floating if the entire side of the GTS transceiver banks are unused.

RCOMP_GTS[L1,R4][A,B,C,D]_N
REFCLK_GTS[L1,R4][A,B,C,D]_CH1p Input/Output

Local reference clock pins for GTS transceiver banks. This pin can be used as an input reference clock pin, or as an output for the CDR recovered clock.

This pin is input-only for banks with the CDRCLKOUT pin.

For more information about the supported pins, refer to the device pin-out file.

AC or DC coupled. Clock driver must be compatible with input requirement in DC coupling case.

Tie to GND if these pins are not used.

REFCLK_GTS[L1,R4][A,B,C,D]_CH1n
CDRCLKOUT_GTS[L1,R4][A,B,C]_CH2p Output

CDR recovered clock output pins for GTS transceiver banks. This pin is only available in certain banks depending on the device variant.

For more information about the supported pins, refer to the device pin-out file.

AC or DC coupled.

Leave unused pins floating.
CDRCLKOUT_GTS[L1,R4][A,B,C]_CH2n
REFCLK_GTS[L1,R4][A,B,C,D]_RX_P Input

Regional reference clock input pins for GTS transceiver banks.

For more information about the supported pins, refer to the device pin-out file.

AC or DC coupled. Clock driver must be compatible with input requirement in DC coupling case.

Tie to GND if these pins are not used.

REFCLK_GTS[L1,R4][A,B,C,D]_RX_N
GTS[L1,R4][A,B,C,D]_RX_CH[0,1,2,3]p Input

GTS transceiver input pins.

For more information about the supported pins, refer to the device pin-out file.

AC or DC coupled.

Tie to GND if these pins are not used.

GTS[L1,R4][A,B,C,D]_RX_CH[0,1,2,3]n
GTS[L1,R4][A,B,C,D]_TX_CH[0,1,2,3]p Output

GTS transceiver output pins.

For more information about the supported pins, refer to the device pin-out file.

AC or DC coupled.

Leave unused pins floating.
GTS[L1,R4][A,B,C,D]_TX_CH[0,1,2,3]n
APROBE_GTS[L1,R4][A,B,C,D]_CH[0,1,2,3] — — Leave these pins floating.
APROBE2_GTS[L1,R4][A,B,C,D] — — Leave these pins floating.
