2.9 JX1, JX2 and JX3 SOM Interface MicroHeaders
The PicoZed Carrier has three 100-pin MicroHeaders (FCI, 61083-101400LF) for connection to
the SOM. The stack height is 5mm for each of these connectors.
•
The JX1 and JX2 connectors interface power control signals, SOM reset, JTAG, PL (FMC
data/control, PB), PS Pmod, Ethernet, and HDMI signals to the SOM target.
•
The JX3 connector interfaces SOM Ethernet, PCIe TX/RX/CLKs, microSD Card, 1 Wire MAC ID,
RTC interrupt, USB OTG, PL I/O, USB UART, Gigabit transceivers data and clocks (MGT/GTX),
and the jumper cabled SFP+ to the JZ PMOD header.
•
The connectors are FCI 0.8mm BergStak
®
, 100 Position, Dual Row, BTB Vertical plugs. These
have variable stack heights from 5mm to 16mm, making it easy to connect to a variety of carrier
or system boards.
•
Each pin can carry 500mA of current. The 5mm stack height is used on the PZCC-FMC-V2, and
PicoZed SOMs support I/O speeds up to 8 Gbps as shown in the following FCI customer
presentation:

•
The fastest supported rate in the PicoZed family exists with the 7030 member, whose Zynq
device/package can achieve 6.6 Gbps. This is within the operating rate of the BergStak
connectors.
•
The carrier card powers the PicoZed PL VCCIO
banks. This gives the carrier card the flexibility to
control the I/O bank voltages. On the PZCC-FMC-V2, both VCCO_34 and VCCO_35 are
powered from a single supply.VCCO_13 is powered from 3.3V.
•
One signal in a Bank 34 differential pair (JX1_LVDS_2_P on 7010/20, JX2_LVDS_2_P on
7015/30) is shared with PUDC_B which is pulled down via a 1K
Ω resistor to ground.
