Description
RX core and PHY reset signal
Reset signal generated to reset the receiver downstream
protocol logic. This generated reset signal is synchronous
to rx_vid_clkout clock domain
Receiver parallel video data out.
Data valid signal generated from SDI RX core and has
the following timing synchronous to rx_vid_clkout:
SD-SDI: 1H 4L 1H 5L
HD/3G/6G/12G-SDI: H
Received video standard.
• 3'b000: SD-SDI
• 3'b001: HD-SDI
• 3'b011: 3G-SDI Level A 10-bit Multiplex
• 3'b010: 3G-SDI Level B 10-bit Multiplex
• 3'b101: 6G-SDI 10-bit Multiplex Type 1
• 3'b100: 6G-SDI 10-bit Multiplex Type 2
• 3'b111: 12G-SDI 10-bit Multiplex Type 1
• 3'b110: 12G-SDI 10-bit Multiplex Type 2
Frame locked indicating multiple frames with same
timing have been spotted.
Horizontal blanking interval timing signal. The receiver
asserts this signal when the horizontal blanking interval
is active.
Vertical blanking interval timing signal. The receiver
asserts this signal when the vertical blanking interval is
active.
Field bit timing signal. This signal indicates which video
field is currently active. For interfaced frame, 0 means
first field (F0) while 1 means second field (F1). For
progressive frame, the value is always 0.
Receiver output signal that indicates current word is TRS.
This signal is asserted at the first word of 3FF 000 000
TRS.
Transmitter parallel video data input
Data valid for the transmitter parallel data. The timing
(H:High, L:Low) must be as follows and synchronous to
tx_pclk clock domain:
SD-SDI: 1H 4L 1H 5L
HD-SDI: 1H 1L (for triple/multi rate)
H (for single rate)
3G/6G/12G-SDI: H
Indicates the desired transmit video standard.
• 3'b000: SD-SDI
• 3'b001: HD-SDI
• 3'b011: 3G-SDI Level A 10-bit Multiplex
• 3'b010: 3G-SDI Level B 10-bit Multiplex
• 3'b101: 6G-SDI 10-bit Multiplex Type 1
