Signals, Interfaces and Pins
Board to Board (B2B) I/O's
The Board to Board connectors are high-speed hermaphroditic stacking strips and provide a modular interface to the SoC's PL and PS I/O's.
The connector supports single ended and differential signaling as the I/O's are usable as LVDS-pairs.
The I/O signals are routed from the SoC's PL banks as LVDS-pairs to the B2B connector.
...

Gigabit Ethernet Interface
On board Gigabit Ethernet PHY is provided with Marvell Alaska 88E1512 IC. The Ethernet PHY RGMII Interface is connected to the Zynq Ethernet0 PS GEM0. I/O voltage is fixed at 1.8V for HSTL signaling. The reference clock input of the PHY is supplied from an on-board 25MHz oscillator (U9), the 125MHz output clock is available on B2B connector J2, pin J2-150.

MAC Address EEPROM
A Microchip 24AA025E48 EEPROM (U23) is used which contains a globally unique 48-bit node address, that is compatible with EUI-48(TM) and EUI-64(TM) 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 address 0x53.
USB Interface
USB PHY is provided by USB3320 from Microchip. The ULPI interface is connected to the Zynq PS USB0. The I/O Voltage is fixed at 1.8V. The reference clock input of the PHY is supplied from an on-board 25 MHz oscillator (U15).

Table 7: USB PHY interface connections
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 USB Micro connector can be used for Device mode, OTG Mode or Host Mode.
RTC - Real Time Clock
An temperature compensated Intersil ISL12020M is used as Real Time Clock (U24). Battery voltage must be supplied to the clock from the base board via pin 'VBAT_IN' (J1-146). Battery backed registers can be accessed over I²C bus at slave address 0x6F. General purpose RAM of the RTC can be accessed at I²C slave address 0x57. RTC IC is supported by Linux so it can be used as hwclock device. The interrupt line 'RTC_INT' of the RTC is connected to System Controller CPLD on bank 3, pin 4.

System Controller CPLD
The System Controller CPLD is the central system management unit on the SoC module which generates control signals and evaluates and handles signals like the "Power Good"-signals of the on-board DC-DC converters. Interfaces between the on-board peripherals and the SoC-module are by-passed, forwarded and controlled by the System Controller CPLD.

Programmable PLL Clock (Phase-Locked Loop)
There is a Silicon Labs I²C programmable quad PLL clock generator Si5338A (U16) on-board. It's output frequencies can be programmed by using the I²C-bus with address 0x70.
A 25 MHz (U21) oscillator is connected to pin 3 (IN3) and is used to generate the output clocks.
Once running, the frequency and other parameters can be changed by programming the device using the I²C-bus connected between the Zynq-module (master) and reference clock signal generator (slave).

Power and Power-On Sequence
Power Supply
Power supply with minimum current capability of 3A for system startup is recommended.
Power Consumption
...
Table 14: Maximum current of power supplies. *to be determined soon with reference design setup.
Lowest power consumption and highest efficiency of on board DC/DC regulators it is recommended to powering the module from one single 3.3V supply. All input power supplies have a nominal value of 3.3V. Although the input power supplies can be powered up in any order, it is recommended to power them up simultaneously.
Power-On Sequence
It is important that all baseboard I/Os are 3-stated at power-on until System Controller sets PGOOD signal high (B2B connector JM1, pin 30), or 3.3V is present on B2B connector JM2 pins 10 and 12, meaning that all on-module voltages have become stable and module is properly powered up.
See Xilinx datasheet DS191 (for XC7Z030) for additional information. User should also check related base board documentation when intending base board design for TE0745 module.
The on-board voltages of the TEC0330 FPGA board will be powered-up in order of a determined sequence after the external voltages '12V' on connector J5 and '3V3PCI' on connector J1 are available.
Core voltages and main supply voltages have to reach stable state and their "Power Good"-signals have to be asserted before other voltages like PL bank's I/O voltages can be powered up.
Following diagram clarifies the sequence of enabling the particular on-board voltages:
Power-up sequence at start-up
The Trenz TE0782 SoM is equipped with two quad DC/DC-voltage-regulators to generate the required on-board voltages with the values 1V, 3.3V, 1.8V, 1.2V_MGT, 1V_MGT.
There are also additional voltage regulators on board to generate the voltages 1.5V, VTT, VTTREF and 1.8V_MGT.
On this SoM the sequence of powering up of the required on-board voltages is handled internally by the system controller CPLD processing the "POWER GOOD"-signals from the voltage-regulators.
The "POWER GOOD"-signals can be checked on the system controller CPLD.
Pay attention to the voltage level of the I/O-signals, which must not be higher then VCCIO+0.4V.
