Signals, Interfaces and Pins

Board to Board (B2B) I/O's

The B2B connectors are high-speed hermaphroditic stacking strips and provide a modular interface to the SoC's PL and PS I/O's supporting single ended and differential signalling as the I/Os are usable as LVDS pairs.

Table 2: Count, type and voltage range of SoC's PL and PS I/O banks pins available through B2B connectors.

For detailed information about the pin-out, please refer to the Pin-out Table.

MGT Lanes

The MGT bank signals of the SoC are routed to the B2B connectors J1 and J3. There are 8 high-speed bi-directional data lanes (Xilinx GTX transceivers) available composed as differential signaling pairs for both directions (RX/TX). On B2B connector J3 there are also clock input pins for MGT transceivers.

Following MGT lanes are available on the B2B connectors:

JTAG Interface

JTAG access is provided through the SoC's PS configuration bank 0 and available on B2B connector J1.

System Controller I/O Pins

Special purpose pins are connected to smaller System Controller CPLD and have following default configuration:

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.

Table 9: Ethernet PHY interface connections

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 10: 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.

I2C Interface

The I²C-interface on the B2B-connector J2 with the pins J2-119 (I2C_33_SCL) and J2-121 (I2C_33_SDA) is operating with the reference voltage PS_3.3V.

Except the RTC, the remaining component's I²C-interfaces are operating with the reference voltage PS_1.8V (voltage level shifting 3.3V ↔ 1.8V via I²C bus repeater U17).

 I2C addresses for on-board devices are listed in the table below:

Table 11:  Module's I²C-interfaces overview

Boot Process

TE0745 module supports different boot modes which are configurable by the control line 'BOOTMODE' and 'BOOTMODE_1'. The line 'BOOTMODE' is available on B2B connector pin J2-133, the line 'BOOTMODE_1' is connected to the System Controller CPLD on bank 1, pin 21.

The current boot mode will be set by the MIO pins MIO3...MIO5. The control line 'BOOTMODE' is connected to the 'MIO4' pin, 'BOOTMODE_1' to 'MIO5'.

Following table describes how to set the control lines to configure the desired boot mode:

Table 12: Selectable boot modes

On-board Peripherals

Flash

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.

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.

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.

For the 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

The on-board voltages of the TE0745 SoC module will be powered-up in order of a determined sequence after the external voltages 'PL_VIN', 'PS_VIN' and 'PS_3.3V' 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.

It is important that all baseboard I/Os are 3-stated at power-on until the "Power Good"-signals 'PWR_PS_OK' (J2-139) and 'PWR_PL_OK' (J2-135) are high, meaning that all on-module voltages have become stable and module is properly powered up.

Following diagram clarifies the sequence of enabling the particular on-board voltages:
