Description
rx_trs_locked
1S
Output
TRS locked, indicating that six consecutive TRSs with same
timing has been spotted.
rx_frame_locked
1
Output
Frame locked, indicating that multiple frames with same timing
has been spotted.
rx_ln
11S
Output
Receiver line number output. Applicable for all modes except
SD-SDI.
rx_ln_b
11S
Output
Receiver line number output for link B. Applicable for 3G-SDI,
HD-SDI dual link, triple standard, and multi standard (up to
12G) modes only.
rx_clkout
1
Output
Receiver CDR clock output.
rx_clkout_b
1
Output
Receiver CDR clock output for link B.
rx_dataout_b
20
Output
Receiver parallel data out for link B. Applicable for HD-SDI dual
link configuration only.
rx_dataout_
valid_b
1
Output
Data valid from the oversampling logic. The receiver asserts this
signal to indicate current data on
rx_dataout_b
is valid. The
timing (H: High, L: Low) for each video standard is identical to
the
rx_dataout_valid
signal.
rx_align_locked_
b
1
Output
Alignment locked for link B, indicating that a TRS has been
spotted and word alignment is performed. Applicable for HD-
SDI dual link configuration only.
rx_trs_locked_b
1
Output
TRS locked for link B, indicating that six consecutive TRSs with
same timing has been spotted. Applicable for HD-SDI dual link
configuration only.
rx_frame_locked_
b
1
Output
Frame locked for link B, indicating that multiple frames with
same timing has been spotted.
rx_dl_locked
1
Output
Dual link locked, indicating that both ports are aligned.
Applicable for HD-SDI dual link configuration only.
rx_trs_loose_
lock_out
1S
Output
Indicates that the receiver protocol block detects a single and
valid TRS locking signal. This signal must be used to drive
rx_
trs_loose_lock_in
of the receiver transceiver block.
rx_trs_loose_
lock_out_b
1
Output
Indicates that the receiver protocol block for link B detects a
single and valid TRS locking signal. This signal must be used to
drive
rx_trs_loose_lock_in_b
of the receiver transceiver block.
Applicable for HD-SDI dual link configuration only.
