- The UHD-SDI RX core hunts for TRS symbols
and asserts
rx_mode_locked
if the UHD-SDI core detects error-free TRS
symbols (that is, a valid XYZ word and with no CRC errors on the received line) for
continuous three video lines.
- Look for pulses on the
rx_eav
, rx_sav
signals at the correct places on each
line along with rx_trs
signal.
- Make sure no CRC errors are reported on
rx_crc_err_ds1
to ds16.
- Make sure supported modes are enabled in
the
rx_mode_enable
[5:0] signal.
- Verify that
rx_mode
[2:0] reported by the SDI core matches the incoming SDI mode.
- SDI Mode detection searches the mode in
the following fashion if all of the modes are set in
rx_mode_enable
: HD
-> 3G -> 6G -> 12GA -> 12GB -> SD -> HD.
- Make sure that
rx_frame_en
signal is asserted High during core operation.
