rx_ln [21:0] Output
Receiver line number output.
HD-SDI: bits 21:11 unused; bits 10:0 LN
Dual link: bits 21:11 unused; bits 10:0 LN
3G-SDI Level A: bits 21:11 unused; bits 10:0 LN
3G-SDI Level B: bits 21:11 LN link A; bits 10:0 LN link B
rx_std_flag_hd_sdn 1 Output
Indicates received standard for dual or triple standard only.
HD-SDI = 1; SD-SDI = 0.
rx_V [1:0] Output
This is a vertical blanking interval timing signal. The
receiver asserts this signal when the vertical blanking
interval is active.
HD-SDI/SD-SDI: bit 1 unused; bit 0 rx_v
Dual link: bit 1 unused; bit 0 rx_v
3G-SDI Level A: bit 1 unused; bit 0 rx_v
3G-SDI Level B: bit 1 link A rx_v; bit 0 link B rx_v
rx_xyz 1 Output Receiver output that indicates current word is XYZ word.
xyz_valid 1 Output
Receiver output that indicates current TRS format is legal
(XYZ word is correct).
rx_eav 1 Output Receiver output that indicates current TRS is EAV.
rx_trs 1 Output
Receiver output that indicates current word is TRS. This
signal is asserted at the first word of 3FF 000 000 TRS.
sdi_tx [(N – 1):0] Output Serial output.
tx_protocol_out [(20N – 1):0] Output Data out (protocol only mode).
