I/O voltage is fixed at 1.8V for HSTL signalling. SGMII (SFP copper or fiber) can be used directly with the Ethernet PHY, as the SGMII pins are available on the B2B connector JM3. The reference clock input of the PHY is supplied from an on-board 25.000000 MHz oscillator (U9), the 125MHz output clock signal CLK_125MHZ is connected to the IN5 pin of the PLL chip (U10).

The schematics for the USB connector and required components is different depending on the USB usage. USB standard A or B connectors can be used for host or device modes. A mini-USB connector can be used for USB device mode. A micro-USB connector can be used for device mode, OTG mode or host mode.

I2C Interface

On-board I²C devices are connected to the Zynq SoC's PS bank 501 MIO48 (SCL) and MIO49 (SDA) which is configured as I2C1 by default. As bank 501 VCC_MIO1_501 is fixed to 1.8V, there is a bi-directional voltage-level translator used to connect 3.3V I²C slave devices to the bus. Table below lists I²C slave device addresses and functions:

A Microchip 24AA025E48 EEPROM (U19) is used which contains a globally unique 48-bit node address compatible with EUI-48TM specification. The device is organized as two blocks of 128 x 8-bit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. It is accessible through the I²C slave device address 0x50.

RTC - Real Time Clock

An temperature compensated Intersil ISL12020M is used for Real Time Clock (U16). Battery voltage must be supplied to the module from the baseboard. Battery backed registers can be accessed over I²C bus at slave address of 0x6F. General purpose RAM is at I²C slave address 0x57. RTC IC is supported by Linux so it can be used as hwclock device.

Power and Power-On Sequence

Power Consumption

Power supply with minimum current capability of 3A for system startup is recommended. Maximum power consumption of a module mainly depends on the design running on the FPGA. Xilinx provides power estimator excel sheets to calculate power consumption. It is also possible to evaluate the power consumption of the design with Vivado. See also Trenz Electronic Wiki FAQ.

Table 15: Typical power consumption.

Power Distribution Dependencies

Figure 3: Module power distribution diagram.

Power-On Sequence

Figure 4: TE0820-02 power-on sequence diagram.

For highest efficiency of the on-board DC-DC regulators, it is recommended to use same 3.3V power source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is recommended to power them up simultaneously.

See Xilinx datasheet DS187 (for XC7Z015) or DS191 (for XC7Z030) for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0715 module.
