Device Under Test (DUT) Components
Component
Description
SDI II
• TX
— The IP core receives the video data from top level and encodes the
necessary information, for example line number, CRC or payload ID into
the data streams.
• RX
— The IP core receives the parallel data from Transceiver Native PHY and
performs necessary decoding, such as descrambling, realigning the data
and extracting the necessary information.
— The output data from these blocks connects to the SDI F-tile PHY adapter
module before passing it to Direct PHY IP.
F-tile PMA/FEC Direct PHY
• TX
— Hard transceiver block which receives the parallel data from SDI core and
serialize the data before transmitting it.
• RX
— Hard transceiver block to receive the serial data from an external video
source.The PHY runs in System PLL clocking mode and system clock
output always runs at a higher clock frequency than the native PMA
recovered clock.

PHY adapter
Adapter block which includes DCFIFO for converting the bit width of parallel data
between transceiver and SDI core, as well as to transfer the data between these
two clock domains.

Video Pattern Generator Components
Component
Description
Video Pattern Generator
Basic video pattern generator which can support SD-SDI up to 12G-SDI video
formats with 4:2:2 YCbCr. You can select static video with colorbar pattern or
pathological pattern from this pattern generator.
Pattern Gen Control PIO
Provides a memory-mapped interface for controlling the video pattern generator.
JTAG to Avalon Master Bridge
Provides System Console host access to the Parallel I/O (PIO) IP in the design
via the JTAG interface.

Common Block
Description
Reference and System PLL Clocks
This IP connects the System PLL output clock as well as the TX PLL and RX CDR
reference clock to the F-tile PMA/FEC Direct PHY IP.
System PLL clock output is always set to run at a higher clock frequency than the
native PMA recovered clock.
