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.

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).

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.
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.
To avoid any demages to the SoC module, check for stabilized on-board voltages in steady state before powering up the SoC's I/O bank voltages VCCO_x. |
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:
