Description
tx_trs_b
1
Input
Transmitter TRS input for link B. For use in HD-SDI dual link
mode LN, CRC, or payload ID insertion. Assert this signal on
first word of both EAV and SAV TRSs.
tx_dataout
20S
Output Transmitter parallel data out.
• Arria V, Cyclone V, and Stratix V devices: Available for
transmitter protocol configuration only.
• Arria 10 devices: Available whenever TX core is included.
tx_dataout_valid
1
Output Data valid generated by the core. This signal can be used to drive
tx_datain_valid
. The timing (H: High, L: Low) must be
synchronous to
tx_pclk
clock domain and have the following
settings:
• SD-SDI = 1H 4L 1H 5L
• HD-SDI = H
• 3G-SDI = H
• HD-SDI Dual Link = H
• Dual standard = SD (1H 4L 1H 5L); HD (1H 1L)
• Triple standard = SD (1H 4L 1H 5L); HD (1H 1L); 3G (H)
• Multi standard (up to 12G) = SD (1H 4L 1H 5L); HD (1H 1L);
3G/6G/12G (H)
tx_dataout_b
20
Output Transmitter parallel data out for link B. Applicable for HD-SDI
dual link transmitter protocol configuration only.
tx_dataout_
valid_b
1
Output Data valid generated by the core for link B. Applicable for HD-
SDI dual link mode only. The timing (H: High, L: Low) is
identical to the
tx_dataout_valid
signal and is synchronous to
tx_pclk
clock domain.
tx_std_out
3
Output Indicates the transmitted video standard. Applicable for 3G-SDI,
dual standard, and triple standard modes only.
tx_vpid_
overwrite
1
Input
When a payload ID is embedded in the video stream, the core
enables this signal to overwrite the existing payload ID. No effect
when disabled.
Applicable only when you enable the Insert Payload ID (SMPTE
352M) option.
tx_vpid_byte1
8S
Input
The core inserts payload ID byte 1.
Applicable only when you enable the Insert Payload ID (SMPTE
352M) option.
tx_vpid_byte2
8S
Input
The core inserts payload ID byte 2.
Applicable only when you enable the Insert Payload ID (SMPTE
352M) option.
