Detailed Description Copyright © 2016–2017, Texas Instruments Incorporated
• Two independently configurable external video input capture slices (Slice 0 and Slice 1) each of which
has two video input ports, Port A and Port B, where Port A can be configured as a 24/16/8-bit port, and
Port B is a fixed 8-bit port.
• Each video Port A can be operated as a port with clock independent input channels (with interleaved or
separated Y/C data input). Embedded sync and external sync modes are supported for all input
configurations.
• Support for a single external asynchronous pixel clock, up to 165MHz per port.
• Pixel Clock Input Domain Port A supports up to one 24-bit input data bus, including BT.1120 style
embedded sync for 16-bit and 24-bit data.
• Embedded Sync data interface mode supports single or multiplexed sources
• Discrete Sync data interface mode supports only single source input
• 24-bit data input plus discrete syncs can be configured to include:
– 8-bit YUV422 (Y and U/V time interleaved)
– 16-bit YUV422 (CbY and CrY time interleaved)
– 24-bit YUV444
– 16-bit RGB565
– 24-bit RGB888
– 12/16-bit RAW Capture
– 24-bit RAW capture
• Discrete sync modes include:
– VSYNC + HSYNC (FID determined by FID signal pin or HSYNC/VSYNC skew)
– VSYNC + ACTVID + FID
– VBLANK + ACTVID (ACTVID toggles in VBLANK) + FID
– VBLANK + ACTVID (no ACTVID toggles in VBLANK) + FID
• Multichannel parser (embedded syncs only)
– Embedded syncs only
– Pixel (2x or 4x) or Line multiplexed modes supported
– Performs demultiplexing and basic error checking
– Supports maximum of 9 channels in Line Mux (8 normal + 1 split line)
• Ancillary data capture support
– For 16-bit or 24-bit input, ancillary data may be extracted from any single channel
– For 8-bit time interleaved input, ancillary data can be chosen from the Luma channel, the Chroma
channel, or both channels
– Horizontal blanking interval data capture only supported when using discrete syncs (VSYNC +
HSYNC or VSYNC + HBLANK)
– Ancillary data extraction supported on multichannel capture as well as single source streams
