1.4.1. Stratix® 10 E-Tile Pins

Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks 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 19.   Stratix® 10 E-Tile Pins
Pin Name Pin Functions Pin Description Connection Guidelines
VCCH_GXE(L2, L3, R1, R2, R3) Power Analog power, block level transmitter buffers for E-Tile, specific to the left (L) side or right (R) side of the device.

Connect VCCH_GXE to a 1.1V low noise switching regulator.

VCCH_GXE must be powered up even when the E-Tile transceivers are not used.

VCCRT_GXE(L2, L3, R1, R2, R3) Power Analog power, used for the high-speed circuitry for the E-Tile blocks, specific to the left (L) side or right (R) side of the device.

Connect VCCRT_GXE to VCCERAM through an LC filter. For more information about the LC filter design, refer to the Stratix® 10 Power Management User Guide .

VCCRT_GXE must be powered up even when the E-Tile transceivers are not used.

VCCRTPLL_GXE(L2, L3, R1, R2, R3) Power Analog power, used for the high-speed circuitry for the E-Tile blocks, specific to the left (L) side or right (R) side of the device.

You must source the VCCRTPLL_GXE from the VCCRT_GXE with proper isolation filtering.

Filtering may be optional if this voltage rail can meet the noise mask requirement. For more information about the noise mask requirements, refer to the Stratix® 10 Power Management User Guide .

VCCRTPLL_GXE must be powered up even when the E-Tile transceivers are not used.

VCCCLK_GXE(L2, L3, R1, R2, R3) Power I/O power, specific to the E-Tile reference clock buffers.

Connect VCCCLK_GXE to a 2.5 V low noise switching regulator.

VCCCLK_GXE must be powered up even when the E-Tile transceivers are not used.

GXE(L8, R9)(A, B, C)_RX_CH[0:23][p,n]

Input High speed differential serial inputs to the receiver circuitry. Specific to the E-Tile transceiver blocks on the left (L) side or right (R) side of the device.

For PAM4, no off-chip AC-coupling capacitor is required provided that the RX input common mode voltage is between (GND + 300 mV) and (VCCH_GXE - 300 mV), and the RX input amplitude differential voltage is less than 1200 mVp-p. For PAM4, the absolute maximum positive voltage at the RX input of the SerDes is VCCH_GXE to maintain linearity.

For NRZ, no off-chip AC-coupling capacitor is required provided that the RX input common mode voltage is between GND and VCCH_GXE, and the RX input amplitude differential voltage is less than 1200 mVp-p. For NRZ, the absolute maximum positive voltage at the RX input to the SerDes is (VCCH_GXE + 300mV) to prevent forward-biasing of the ESD diodes.

For more information, refer to the Electrical Characteristics section in the Stratix® 10 Device Datasheet .

When the RX input common mode voltage is outside its required range (PAM4 or NRZ), external AC-coupling capacitors must be used. When using external AC-coupling capacitors, the RX termination is to the VCCH_GXE supply. A typical value of 100 nF can be used as the external AC-coupling capacitor. Select a capacitor package (SMD) similar to that of the trace width to reduce in-line parasitics, and a material of X7R quality or higher. For high speed SerDes, mounting launch pad must be carefully designed.

For more information about the external AC-coupling, refer to the E-Tile Transceiver PHY User Guide .

Leave unused pins floating.
GXE(L8, R9)(A, B, C)_TX_CH[0:23][p,n] Output High speed differential serial outputs from the transmitter circuitry. Specific to the E-Tile transceiver blocks on the left (L) side or right (R) side of the device. Leave all unused GXE_TX[p,n] pins floating.
REFCLK_GXE(L8,R9)(A,B,C)_CH[0:8][p,n] Input

High speed differential reference clock connects to the E-Tile transceiver of the left (L) side or right (R) side of the device.

REFCLK_GXE is supplied to both RX and TX independently.

REFCLK_GXE can be used as dedicated clock input pins for core clock generation by configuring transceiver channel (Native PHY IP core) in the PLL mode.

Supported I/O standard:

  • LVPECL

No off-chip AC-coupling capacitor is required. The default internal REFCLK inputs are 2.5-V LVPECL with a 50-Ω termination.

Optional external termination is 2.5-V LVPECL or 3.3-V LVPECL. For more information about the external termination, refer to section 4.1 in the E-Tile Transceiver PHY User Guide .

Tie each unused REFCLK pin to GND through a 1-kΩ resistor.

REFCLK[1] must always be bonded out on board and connected to a clock source in case dynamic reconfiguration of REFCLK is planned. For more details on how to use it, refer to the Dynamic Reconfiguration Flow for Special Cases section in the E-Tile Transceiver PHY User Guide .

Preservation of unused transceiver channels may need extra REFCLK_GXE to be bonded out on board based on use cases. For more details, refer to Unused Transceiver Channel in the E-Tile Transceiver PHY User Guide .

The input reference clock must be stable and free-running at device power-up for proper PLL calibrations and a successful configuration.

IO_AUX_RREF(11, 12, 20, 21, 22) Input Reference resistor for the AIB auxiliary channel. Connect to a 2-kΩ resistor (±1%) to GND.
