Signals, Interfaces and Pins

FMC HPC Connector

The FMC (FPGA Mezzanine Card) connector J5 with high pin count (HPC) provides as an ANSI/VITA 57.1 standard a modular interface to the MPSoCs FPGA and exposes numerous of its I/O pins for use by other mezzanine modules and expansion cards.

The connector supports single ended (VCCIO: FMC_VADJ) and differential signaling as the I/O's are usable as LVDS-pairs.

The I/O signals are routed from the FPGA banks as LVDS-pairs to the connector.

Figure 2: FMC HPC Connector

Table 2: FMC connector pin-outs of available logic banks of the MPSoC

The MGT-banks have also clock input-pins which are exposed to the FMC connector. Following MGT-lanes are available on the FMC connectors J5:

Table 2: FMC connector pin-outs of available MGT-lanes of the MPSoC

The FMC connector provides pins for reference clock output to the Mezzanine module and clock input to PL banks of the MPSoC:

Table 3: FMC connector pin-outs for reference clock output

The FMC connector provides further interfaces like 'JTAG' and 'I²C' to the System Controller CPLD:

Table 4: FMC connector pin-outs of available interfaces to the System Controller CPLD

Several VCCIO voltages are available on the FMC connector to operate the I/O's in order of the intended purpose:

Table 5:  Available VCCIO voltages on FMC connector

MIO Bank Interfaces

The TEBF0808 carrier board provides several interfaces, which are configured on the MIO banks 500 .. 503 of the Zynq Ultrascale+ MPSoC.

Following table contains the assignment of the MIO pins to the configured interfaces:

Table 5:  MIO Assignment

On the carrier board there are up to 4 USB3.0 Super Speed ports available, which are also downward compatible to USB2.0 High Speed ports. The USB3.0 ports are provided by the IC U4, Cypress Semiconductor CYUSB3324 4-port USB3.0 Hub. The pin-strap configuration option of the USB3.0 Hub U4 is disabled, so the Hub will only be configurable over the configuration EEPROM U5. The I²C interface of the EEPROM is also accessible by the MPSoC through I²C switch U16.

On the Upstream-side, this chip is connected to the MGT1 lane of MPSoC's PG GT bank 505 to establish the USB3.0 data lane. For the USB2.0 interface, the USB3.0 HUB U4 is connected to the on-board USB2.0 PHY U9. The USB2.0 PHY U9 is connected per ULPI interface (MIO pins 52..63) to MPSoC's MIO bank 501.

Further interfaces of the MIO bank:

• SDIO port with muxed MikroSD and MMC Socket
• Gigabit Ethernet connected per RGMII
• eMMC Memory
• 4 x user configuration EEPROMs with I²C interface

Following block-diagram visualizes the interfaces of the MIO bank at the Zynq Ultrascale+ MPSoC and their associated on-board peripherals.

Figure 3: TEBF0808 MIO Interfaces

MPSoC's PS GT Bank 505 Interfaces

On the PS GT Bank 505 provides beside the USB3.0 Lane also following interfaces:

• SATA (PS GT bank 505, MGT2 Lane)
• Display-Port (PS GT bank 505, MGT3 Lane, only TX-pair routed)
• PCI Express (PS GT bank 505, MGT0 Lane)
  
  

Table 6:  PS GT Lane Assignment

Following block diagram shows the wiring of the MGT Lanes of the PS GT bank 505 to the particular high speed data interfaces:

Figure 4: TEBF0808 PS GT Bank 505 Interface

MGT Interfaces SFP+ and Firefly

The TEBF0808 carrier board provides the high speed MGT interface connectors "SFP+" (Enhanced small form-factor pluggable) and Samtec "FireFly". Each of this connectors are capable of data transmission rates up  to 10 Gbit/s.

Table 6:  MGT Lane Assignment

Following block diagram show the wiring of the MGT lanes to the particular interface connectors:

Figure 5: TEBF0808 MGT Interfaces

As shown on the block diagram, the FireFly connector pair J21, J22 provides four reversed looped back MGT lanes. To test any of the on-board MGT lanes or of an extern device, 4 RX/TX differential pairs are bridged on the connector, hence the transmitted data on these MGT lanes flows back to their sources in a loop-back circuit without intentional processing or modification.

CAN FD Interface and PMOD Connectors

On the carrier board there is a CAN FD (CAN with Flexible Data-Rate) interface available which is accessible on the CAN headers J24 (10-pin IDC connector) or J29 (6-pin header), which are connected to the CAN FD transceiver U30.

Additionally the carrier board provides PMOD connectors with GPIO and I²C interface. Following table

Table 7:  PMOD Pin Assignment

Figure 6: TEBF0808 CAN Interfaces, PMOD

Intel PC Compatible Headers and FAN Connectors

The TEBF0808 carrier board provides with its Mini-ITX form factor the possibility to encase the board in a PC Enclosure. For this purpose, the board is equipped with several Intel PC compatible headers to connect them to the PC Enclosure.

Pins are available for following PC front panel elements

• Reset Button
• Power Button
• Power LED
• Hard Disc (HD) LED
• Intel High Definition Audio (HDA) Jacks

Following table gives an overview about the particular pins of the headers and a description about their functionalities:

Table 8: PC compatible Headers

Figure 7: TEBF0808 PC Compatible Headers

JTAG Interface

The TEBF0808 carrier board provides several JTAG interfaces to program both the System Controller CPLDs and the Zynq Ultrascale+ MPSoC.

Therefore, the board is equipped with two JTAG/UART headers, which have 'XMOD FTDI JTAG Adapter'-compatible pin-assignment. So in use with the XMOD-FT2232H adapter-board TE0790 the mounted SoM and the System Controller CPLDs can be programmed via USB interface.

The System Controller CPLDs will be programmed by the XMOD-Header J28 with cascaded JTAG chain as visualized in Figure 8. To program the System Controller CPLDs, the JTAG interface of these devices have to be activated by DIP-switch S4-3.
The 4 GPIO/UART pins (XMOD1_A/B/E/G) of the XMOD-Header J28 are routed to the System Controller CPLD U17.

XMOD-Header J12 is designated to program the Zynq Ultrascale+ MPSoC via USB interface, the 4 GPIO/UART pins (XMOD2_A/B/E/G) of this header are routed to the System Controller CPLD U39.

Figure 8: TEBF0808 JTAG interfaces

Further JTAG interfaces of the TEBF0808 carrier board are the ARM JTAG 20-pin IDC connector J30 and on the FMC Connector J5. This JTAG interfaces are connected to the System Controller CPLD U17, hence the logical processing and forwarding of the JTAG signals depend on the SC CPLD firmware. The documentation of the SC CPLD U17 contains detailed information on this matter.
