Description
User-supplied transmitter parallel data. SD-SDI uses 9:0;
HD-SDI uses 20 N – 1:0.
SD: bits 19:10 unused; bits 9:0 Cb, Y, Cr, Y multiplex
HD: bits 19:10 Y; bits 9:0 C
txdata
[(20 N – 1):0]
Input
Dual link: bits 39:30 Y link B; bits 29:20 C link B;

insertion. Assert on first word of both EAV and SAV TRSs.
Refer to Figure 3–31 and Figure 3–32 .
Transmitter standard. 00 for SD-SDI; 01 for HD-SDI; 11 for
tx_std
[1:0]
Input
3G-SDI Level A, and 10 for 3G-SDI Level B. This signal
must be set up and stable prior to device bring-up or core
reset. Refer to Figure 3–31 and Figure 3–32 .
TRS locking signal for protocol only receiver mode. You

can connect this signal to the rx_protocol_locked pin
of the transceiver only receiver block.
CRC error on luma channel.
HD-SDI: bit 1 unused; bit 0 crc_error_y
Dual link: bit 1 link B crc_error_y ; bit 0 link A
crc_error_y
[1:0]
Output
crc_error_y
3G-SDI Level A: bit 1 unused; bit 0 crc_error_y
3G-SDI Level B: bit 1 link A crc_error_y ;
