Signal Width Direction Description

rx_dataout_valid

1 Output Data valid from the oversampling logic. The receiver asserts this

signal to indicate current data on rx_dataout is valid. The

timing (H: High, L: Low) for each video standard has 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 (H)

• Triple standard = SD (1H 4L 1H 5L); HD (H); 3G (H)

• Multi standard (up to 12G) = SD (1H 4L 1H 5L); HD (1H 1L);

3G/6G/12G (H)

rx_f

1 Output Field bit timing signal. This signal indicates which video field is

currently active. For interlaced frame, 0 means first field (F0)

while 1 means second field (F1). For progressive frame, the value

is always 0.

rx_v

1 Output Vertical blanking interval timing signal. The receiver asserts this

signal when the vertical blanking interval is active.

rx_h

1 Output Horizontal blanking interval timing signal. The receiver asserts

this signal when the horizontal blanking interval is active.

rx_ap

1 Output Active picture interval timing signal. The receiver asserts this

signal when the active picture interval is active.
