The MIPI CSI-2 bus is passively terminated on the Zybo Z7 and connected directly to the Zynq PL. The guidelines
described in Xilinx application note
XAPP894 D-PHY solutions
were followed in order to implement a compatible D-
PHY receiver using the Zynq. The interface is tested to operate at up to 672 mbps on each lane. Speeds up to 950
mbps on each lane are possible based on the Zynq-7000 timing specifications, however they are not validated on
the Zybo Z7.
A
MIPI CSI-2 Receiver IP core
is available from Xilinx, and includes embedded Linux support. It requires a license in
order to use; however, it is possible to obtain an evaluation license from Xilinx for free.
Note: Digilent does not currently have any Pcam modules available for sale, and therefore no demo content
either. The expected release date of our first Pcam module is at the end of 2017. This Pcam module will be
released with demo content for use with the Zybo Z7. We apologize for the delay.
16 Pmod Ports
Pmod ports are 2×6, right-angle, 100-mil spaced female connectors that mate with standard 2×6 pin headers. Each
12-pin Pmod port provides two 3.3V VCC signals (pins 6 and 12), two Ground signals (pins 5 and 11), and eight logic
signals, as shown in Figure 16.1. The VCC and Ground pins can deliver up to 1A of current, but care must be taken
not to exceed any of the power budgets of the on-board regulators or the external power supply (these are
described in the “Power supplies” section).
Figure 16.1. Pmod port.
Digilent produces a large collection of Pmod accessory boards that can attach to the Pmod ports to add ready-
made functions like A/D’s, D/A’s, motor drivers, sensors, and other functions. See
digilentinc.com
for more
information. The vivado-library repository on the
Digilent Github
contains pre-made IP cores for many of these
Pmods that greatly reduces the work of integrating them into your project. See the “Using Pmod IP” tutorial on the
Zybo Z7 Resource Center for help using them.
The Zybo Z7 has six Pmod ports, some of which behave differently than others. Each Pmod port falls into one of
four categories: standard, MIO connected, XADC, or high-speed. Table 16.1 specifies which category each Pmod
port falls into, and also lists the Zynq pins they are connected to. The sections that follow describe the different
types of Pmods.
