7.4.12 RAW Mode LV / FV Controls

The Raw modes provide FrameValid (FV) and LineValid (LV) controls for the video framing. The FV is equivalent to a Vertical Sync (VSYNC) while the LineValid is equivalent to a Horizontal Sync (HSYNC) input to the DVP Mode serializer.

The TDES960 allows setting the polarity of these signals by register programming. The FV and LV polarity are controlled on a per-port basis and can be independently set in the PORT_CONFIG2 register 0x7C.

To prevent false detection of FrameValid, FV must be asserted for a minimum number of clocks prior to first video line to be considered valid. The minimum FrameValid time is programmable in the FV_MIN_TIME register 0xBC. Because the measurement is in V3LINK clocks, the minimum FrameValid setup to LineValid timing at the Serializer will vary based on operating mode.

A minimum FV to LV timing is required when processing video frames from a RAW serializer input. If the FV to LV minimum setup is not met (by default), the first video line is discarded. Optionally, a register control (PORT_CONFIG:DISCARD_1ST_ON_ERR) forwards the first video line missing some number of pixels at the start of the line. There is no timing restrictions at the end of the frame.

For other settings of FV_MIN_TIME, use Equation 1 to determine the required FV to LV setup in Serializer PCLKs.

Equation 1. Absolute Min + (FV_MIN_TIME × Conversion factor)

The minimum LV to FV timing requirement for all three RAW modes is 0. See Table 7-12 for the exact timing in Serializer PCLKs.
