◙ 7.0) FPGA Mezzanine Card (FMC+) Interface (Vita57.4) The HTG-ZRF8 platform is populated with one Vita57.4 compliant FMC+ connector with 68 single-ended I/Os and 8 GTY (32.75Gbps) Serial Transceivers. This expansion port hosts Vita57.1 or Vita57.4 compliant daughter cards. HiTech Global offers wide range of add-on FMC and FMC+ modules as shown on http://www.hitechglobal.com/Accessories/FMC_Modules.htm...
HTG-ZRF8 Platform User Manual 7.1) FMC+ Clock Clocks for the FMC+ I/Os are generated by the onboard Si5341 programmable clock generator through OUT2 (FMC_PL_REFCLK_C2M) , OUT3 (GTY_131_REFCLK) and OUT4 (GTY_130_REFCLK) ports as shown by figure (5) and table (3). 7.2) FMC VADJ V_Adjust carries an adjustable voltage level power from the FPGA carrier board to the I/O Mezzanine modules.
HTG-ZRF8 Platform User Manual ◙ 8.0) ADC and DAC Ports The HTG-ZRF platform provides access to eight 12-bit ADC (4GSPS) and eight 14-bit DAC (6.4GSPS) ports through sixteen SSMC connectors. The ADC and DAC ports are supported through high-performance front panel Mini Circuits TCM1-83X+ micro Rf connectors (with bandwidth from 10 to 8000 MHz).
9.0) USB To UART Bridges The HTG-ZRF8 platform provides access to two UART ports for the PL and PS sides through two peripheral USB connectors (J1 and J12). These ports are supported by the Silicon labs CP2103 USB to UART controller chips (U70 and U71).
◙ 10.0) ARM Trace Port The HTG-ZRF8 provides access to one standard ARM Trace/Debug port (38-pin Mictor connector). The pin out follows the single target connector pinout specification as defined in the ARM "Architecture Specification. Table (14) illustrates FPGA pin assignment for the ARM Trace/Debug port (J22)
◙ 11.0) SDIO Interface The HTG-ZRF8 supports a secure digital input/output (SDIO) interface providing access to general purpose non-volatile SDIO memory cards and peripherals. The SDIO signals are connected to the PS bank 501 of the onboard Zynq UltraScale+ FPGA. A SD 2.0-compliant voltage level-translator (SN74AVCA406EZQS) is present between the onboard Zynq UltraScale+ RFSoC FPGA and the SD card connector (J35).
◙ 12.0) 10/100/1000 Mbps Ethernet The HTG-ZRF8 platform provides access to one 10/100/1000 Mbps Ethernet port (J30) supported by Texas Instruments DP83867IRPAP PHY chip connected to the processor’s I/Os of the FPGA. The DP83867 device is a fully featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX and 1000BASE-T Ethernet protocols.
◙ 14.0) USB 2.0/3.0 The HTG-ZRF8 platform provides access to a USB 2.0 through Microchip USB3320 chip and USB 3.0 through GTR serial transceivers of the FPGA’s processor side. The Microchip USB3320 is a USB 2.0 Transceiver that provides a configurable physical layer (PHY).
