Table 1. UHD-SDI Audio (Extract) I/O Signal Description
Port Name	Width	I/O	Description
sdi_extract_clk	1	Input	This is the video clock
sdi_extract_reset	1	Input	Video reset, Active-High
sdi_extract_anc_ctrl_in	32	Input	Ancillary control information from the AMD UHD SDI Receiver Subsystem. You must populate these signals manually when UHD-SDI RX Subsystem is not used. [0] - `rx_ce`. This signal is the video clock enable from the receiver [3:1] - `rx_mode`. This signal indicates the current SDI mode of the receiver 000 = HD 001 = SD 010 = 3G 100 = 6G 101 = 12G 1000/1000 110 = 12G 1000/1001 [7:4] - `rx_t_family`. This signal indicate the video format family 0000 - SMPTE ST 274 1920 x 1080 0001 SMPTE ST 296 1280 x 720 0010 SMPTE 2048-2 2048 x 1080 0011 SMPTE 295 1920 x 1080 1000 NTSC 720 x 486 1001 PAL 720 x 576 1111 Unknown [8] - `rx_mode_locked`. When the receiver locks to the correct SDI mode, the `rx_mode_locked` goes High. [9] `rx_t_locked`. This signal is 1 when the transport detection function in the receiver has identified the transport format of the SDI signal
sdi_extract_anc_ctrl_in (cont'd)	32	Input	[13:10] `rx_t_rate`. This signal indicates the frame rate of the transport. 0000 - None 0010 - 23.98 Hz 0011 - 24 Hz 0100 - 47.95 Hz 0101 - 25 Hz 0110 - 29.97 Hz 0111 - 30 Hz 1000 - 48 Hz 1001 - 50 Hz 1010 - 59.94 Hz 1011 - 60 Hz Others - Reserved [14] `rx_t_scan`. This signal indicates whether the transport is interlaced (Low) or progressive (High). [15] - `rx_rst_int_sys`. This signals indicates that UHD-SDI RX Subsystem is under reset. When UHD-SDI RX Subsystem is not used, connect this to `rx_fabric_rst_out` from drp control engine.. [16] `rx_level_b_3g`. In 3G-SDI mode, this output is asserted High when the input signal is level B and Low when it is level A. [19:17] `rx_act_streams`. This signal indicates the number of data streams that are active for the current video format being received. 000 - 1 active stream 001 - 2 active streams 010 - 4 active streams 011 - 8 active streams 100 - 16 active streams [31:20] reserved
sdi_extract_anc_ds1_in	10	Input	Data stream 1. In SD mode this is interleaved Y/C. In HD and 3GA modes, this is the Y channel. In 3GB mode, this is the link A Y channel. In 6G and 12G modes, this is ds1.
sdi_extract_anc_ds2_in	10	Input	Data stream 2. Not used in SD mode. In HD and 3GA modes, this is the C channel. In 3GB mode, this is the link A C channel. In 6G and 12G modes, this is ds2.
sdi_extract_anc_ds3_in	10	Input	Data stream 3. Not used in SD, HD, and 3GA modes. In 3GB mode, this is the link B Y channel. In 6G and 12G modes this is ds3.
sdi_extract_anc_ds4_in	10	Input	Data stream 4. Not used in SD, HD, and 3GA modes. In 3GB mode, this is the link B C channel. In 6G and 12G modes this is ds4.
