Output
1
Data valid signal generated from SDI TX core and has
the following timing synchronous to tx_vid_clkout:
• SD-SDI: 1H 4L 1H 5L
• HD-SDI: 1H 1L (for triple/multi rate)
• H (for single rate)
• 3G/6G/12G-SDI: H
sdi_rx_align_locked
Output
1
Alignment locked indicating a TRS has been spotted and
word alignment performed.
