Specifications

The frame phase relationship between the SDI video stream and the analog
reference signal is established according to SMPTE RP 168-2002. This
defines the SDI video frame start occurring N pixel periods before the
frame start of the analog video reference signal. N is defined for each video
format in

Table 6

.

Electrical Length

Input to output delay: Default with zero user input delay

In delay mode or in genlock mode with zero input video delay with respect to genlock frame position)

Full-frame mode

1 frame periods in all formats

Minimum delay mode

~ 300 pixel periods in all formats

Input to output delay: User input delay in pixel steps ranging from 0 to 1 frame

1

In delay mode or in genlock mode with any input video delay with respect to genlock frame position

Full-frame mode

1 frame minus 5 lines to 2 frames minus 5 lines

2

Minimum delay mode

~ 300 pixels to 1 frame

Power

Power dissipation

22 W

Frame type

2000T1DNG or 2000T3NG Kameleon frame

Environmental

Operating temperature

Refer to Kameleon 2000 frame specifications

Operating humidity

0 to 90%, non-condensing

1

The User input delay is specified as 1 full frame. plus one frame in pixels and lines. The Delay Wrap Position

on the Frame Sync web page roughly indicates what fraction of that last frame of adjustable delay is being used.
Because the input video delay with respect to genlock frame position can vary, the Delay Wrap Position with
respect to User Input Delay will vary.

2

Full Frame Mode always has at least 1 frame minus 5 lines of electrical length.
