eMMC Flash Memory
eMMC Flash memory device(U6) is connected to the ZynqMP PS MIO bank 500 pins MIO13..MIO23. eMMC chips IS21ES08G-JCLI (FLASH - NAND Speicher-IC (64 Gb x 1) MMC ) is used.
Programmable Clock Generator
There is a Silicon Labs I2C programmable clock generator Si5338A (U10) chip on the module. It's output frequencies can be programmed using the I2C bus address 0x70 or 0x71. Default address is 0x70, IN4/I2C_LSB pin must be set to high for address 0x71.
A 25.00 MHz oscillator is connected to the pin IN3 and is used to generate the output clocks. The oscillator has its output enable pin permanently connected to 1.8V power rail, thus making output frequency available as soon as 1.8V is present. Three of the Si5338 clock outputs are connected to the FPGA. One is connected to a logic bank and the other two are connected to the GTR banks.
Once running, the frequency and other parameters can be changed by programming the device using the I2C bus connected between the FPGA (master) and clock generator (slave). For this, proper I2C bus logic has to be implemented in FPGA.
