I2C Clock Configuration EEPROM – U14
EEPROM I2C ADDR:
0xA0
The clock configuration EEPROM is a Microchip 24AA025T-I/OT and is used to configure U13
when powered up.
•
Base default address:
0xA0
•
Base address adjustable set through JT3 and JT4.
•
If desired, the user can change the timing of the synthesizer via IDT’s Timing
Commander Tool via the on board HDMIO I2C bus or by populating J14 and
connecting directly to the HDMIO I2C bus.
•
For more information on how to custom program the clock, a reference design and

2.5 PCIe x1 Gen2 Interface
Note: The PCIe data interface is available when using a PicoZed 7015 or 7030 SOM.
•
The PCIe x1 interface is
not
required for normal operation. However, it has been
provided to assist in the development of PCIe based SOM products if desired. When
inserted into a PCIe slot, 12V power from the host PCIe slot can be used for low power
applications (10 Watts or less per the PCIe specification Version 1.1). The PCIe interface
includes a 12V power circuit, control signals and a single data lane (differential TX and
RX) and one differential PCIe clock.
For PCIe applications needing more than 10 Watts, use the included
ATX-to-6P Mini-Fit
adapter. Connect the 6P end of the adapter to J2. Connect the 4-pin ATX connector to
the ATX power supply. This will provide supplemental 12V power to the PZCC-FMC-V2.
