This option is available only when you target an Stratix® 10 device that supports both H-tile and E-tile. Select the transceiver tile you want for your design.

When you select E-tile, you can only use soft PCS.

PLL/CDR Reference Clock Frequency

Variable

Set the transceiver reference clock frequency for PLL or CDR.

  • For Stratix® V, Arria® V, and Cyclone® V devices, the frequency range available for you to choose depends on the PLL type and data rate that you select.
  • For Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices, the frequency range available for you to choose depends on the data rate.

VCCR_GXB and VCCT_GXB Supply Voltage for the Transceiver

  • 1.1V
  • 1.0V
 Select the supply voltage for the transceiver.

For details about the minimum, typical, and maximum supply voltage specifications, refer to the Stratix® 10 Device Datasheet.

Note: Available only for Stratix® 10 L-tile and H-tile devices.

Enable Bit reversal and Byte reversal

On, Off

The JESD204B IP uses four 10-bit symbols (denoted as symbol3, symbol2, symbol1, and symbol0) for the 8B/10B encoding scheme. Symbol0 is the first symbol to be shifted out through the serial link while symbol3 is the last symbol to be shifted out.

  • Turn off this option to set the data transmission order to start from the least significant bit (lsb) of each symbol. For example, symbol0[0] is shifted out first, followed by symbol0[1], and so on until the entire symbol0 is shifted out. The transmission continues with symbol1[0] through symbol3[9].
  • Turn on this option to set the data transmission order to start from the most significant bit (lsb) of each symbol. For example, symbol0[9] is shifted out first, followed by symbol0[8], and so on until the entire symbol0 is shifted out. The transmission continues with symbol1[9] through symbol3[0].
Enable Transceiver Dynamic Reconfiguration

On, Off

Turn on this option to enable dynamic data rate change. For V series devices, when you enable this option, you need to connect the reconfiguration interface to the transceiver reconfiguration controller. 18

For Arria® 10, Cyclone® 10 GX, and Stratix® 10 devices, turn on this option to enable the Transceiver Native PHY reconfiguration interface.

Enable Native PHY Debug Master Endpoint 19 On, Off Turn on this option for the Transceiver Native PHY IP core to include an embedded Native PHY Debug Master Endpoint. This block connects internally to the Avalon® memory-mapped slave interface of the Transceiver Native PHY and can access the reconfiguration space of the transceiver. It can perform certain test and debug functions via JTAG using System Console.

This parameter is valid only when you turn on the Enable Transceiver Dynamic Reconfiguration parameter.

Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
Share Reconfiguration Interface 19 On, Off

When enabled, Transceiver Native PHY presents a single Avalon® memory-mapped slave interface for dynamic reconfiguration of all channels. In this configuration the upper address bits ( Stratix® 10: [log2<L>+10:11]; Arria® 10/ Cyclone® 10 GX: [log2<L>+9:10]) of the reconfiguration address bus specify the selected channel. The upper address bits only exist when L>1. Address bits ( Stratix® 10: [10:0]; Arria® 10/ Cyclone® 10 GX: [9:0]) provide the register offset address within the reconfiguration space of the selected channel. L is the number of channel.

When disabled, the Native PHY IP core provides an independent reconfiguration interface for each channel. For example, when a reconfiguration interface is not shared for a four-channel Native PHY IP instance, reconfig_address[9:0] corresponds to the reconfiguration address bus of logical channel 0, reconfig_address[19:10] correspond to the reconfiguration address bus of logical channel 1, reconfig_address[29:20] corresponds to the reconfiguration address bus of logical channel 2, and reconfig_address[39:30] correspond to the reconfiguration address bus of logical channel 3.

For configurations using more than one channel, this option must be enabled when you turn on Enable Native PHY Debug Master Endpoint.

Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
Provide Separate Reconfiguration Interface for Each Channel On, Off When enabled, transceiver dynamic reconfiguration interface presents separate clock, reset, and Avalon® memory-mapped slave interface for each channel instead of a single wide bus. This option is only available when Share Reconfiguration Interface is turned off.
Note: Available in Quartus® Prime Pro Edition only.
Enable Capability Registers 19 On, Off Turn on this option to enable capability registers, which provides high level information about the transceiver channel's configuration.
Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
Set user-defined IP identifier 0–255 Set a user-defined numeric identifier that can be read from the user identifier offset when you turn on the Enable Capability Registers parameter.
Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
Enable Control and Status Registers 19 On, Off Turn on this option to enable soft registers for reading status signals and writing control signals on the PHY interface through the embedded debug. For more information, refer to the respective Transceiver User Guides.
Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
Enable PRBS Soft Accumulators 19 On, Off Turn on this option to set the soft logic to perform pseudorandom binary sequence (PRBS) bit and error accumulation when using the hard PRBS generator and checker.
Note: Available only for Agilex™ 7, Stratix® 10, Cyclone® 10 GX, and Arria® 10 devices.
