VV5301 & VV6301

Clock divisor = 1, 2, 4 or 8.

Conversion factor = 8 for 8-bit ADC accuracy

Output format factor is 2

Example: Pixel period = (2 x 8 x 2) / 14.318MHz = 2.235µs

3.

Line period = (no. of visible pixels + line overhead) x pixel period

The number of visible pixels per line is 160. The interline pixel period overhead (including the 4 border pixels that can be enabled

to qualify extra video information) is mode dependent, 43 pixel periods for 60Hz mode or 141 pixel periods for 50Hz mode.

Example: Line period = (160 + 43) x 2.235µs = 453.705µs

4.

Frame period = (no. of visible lines + frame overhead) x line period

For the purposes of calculating the effective frame rate the number of active lines is assumed to be fixed at 120. The frame

overhead (which includes the 4 border lines that can be enabled to qualify extra video information) has a constant value of 27 line

periods.

Example: Frame period = (120 + 27) x 453.705µs = 66.694ms

giving a frame rate = 1 / frame period = 15 frames per second
