VCCR_GXB[L1,R4] [C,D,E,F,G,H,I,J,K,L,M,N] | VCCR_GXBL1[C,D,E]_T[1,3] VCCR_GXBL1[K,L,M]_T[2,4] |
Power | Analog power, receiver, specific to each transceiver bank of the left (L) side or right (R) side of the device. |
Connect the VCCR_GXB pins to a 1.03-V or 1.12-V low noise switching regulator depending on the transceiver data rate. The VCCR_GXB and VCCT_GXB pins of each bank within a transceiver tile (L-Tile or H-Tile) must have the same voltage (either 1.03 V or 1.12 V). However, VCCR_GXB and VCCT_GXB of different banks within the same transceiver tile can have different voltages based on the configured transceiver data rates to further reduce power consumption of the transceiver tile. When the banks within a transceiver tile are powered at different voltages (for example, some banks operating at 1.03 V while other banks operating at 1.12 V), the xN clock lines are only allowed to transverse between contiguous banks operating at the same VCCR_GXB or VCCT_GXB voltages. The xN clock lines crossing boundaries of banks operating at different voltages is not allowed. For any input reference clock coming into a transceiver tile, that clock can be distributed to any bank within the tile even if the VCCR_GXB and VCCT_GXB operating voltages of the banks are different. When all of the transceivers on the same tile are not used, you may power down the transceivers in that tile by connecting its VCCR_GXB, VCCT_GXB, and VCCH_GXB to GND. Place a 22-nF decoupling capacitor between each VCCR_GXB power pin and GND pin on the back side of the BGA pin field. The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-Tile or H-Tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile. For more information about the voltage requirement for your specific use case, refer to the Stratix® 10 Device Datasheet. See Notes 2, 3, 4, 7, and 10 in Notes to Stratix® 10 Core Pins. |

Power | Analog power, transmitter, specific to each transceiver bank of the left (L) side or right (R) side of the device. | Connect the VCCT_GXB pins to a 1.03-V or 1.12-V low noise switching regulator depending on the transceiver data rate. The VCCR_GXB and VCCT_GXB pins of each bank within a transceiver tile (L-Tile or H-Tile) must have the same voltage (either 1.03 V or 1.12 V).

VCCH_GXB[L1,R4][C,D,E,F,G,H,I,J,K,L,M,N] | VCCH_GXBL1_T[1,3] VCCH_GXBR1_T[2,4] |
Power | Analog power, block level transmitter buffers, specific to the left (L) side or right (R) side of the device. | Connect VCCH_GXB to 1.8-V low noise switching regulator. With a proper isolation filtering, you have the option to source VCCH_GXB from the same regulator as VCCPT. To minimize the regulator switching noise impact on channel jitter performance, keep the switching frequency for VCCH_GXB regulator below 2 MHz. For OTN applications, the switching frequency for VCCH_GXB is recommended to be below 500 KHz. Place a 22-nF decoupling capacitor between each VCCH_GXB power pin and GND pin on the back side of the BGA pin field. A leakage voltage may be observed on the VCCH_GXB power rail before the VCCH_GXB is powered on due to leakage inside the device during the power-up and power-down sequencing. The total magnitude of this leakage voltage is lower than VCCH_GXB and this is an expected behavior. During the power-up sequence only, a transient current whose magnitude is less than the VCCH_GXB static operating current may be observed. The floating voltage and transient current are expected behavior and can neither cause any functional failure nor reliability concerns to the device provided that the power-up or power-down sequence is followed. When all of the transceivers on the same tile are not used, you may power down the transceivers in that tile by connecting its VCCR_GXB, VCCT_GXB, and VCCH_GXB to GND.

These pins should be AC-coupled when connected to any I/O standard other than the HCSL I/O standard. For the HCSL I/O standard, these pins must be DC-coupled. For example, PCIe* reference clocks should be DC-coupled if it uses the HCSL I/O standard. Connect each unused REFCLK_GXB pin to GND plane directly on its own via. Do not share vias when connecting to GND. The input reference clock must be stable and free-running at device power-up for proper PLL calibrations and a successful configuration. For PCIe* , you must follow this clock requirement. See Note 9 in Notes to Stratix® 10 Core Pins. |
