(1) Related with the input maximum frequency supported by the ISP module in 8-bit mode with 8 to 16 data bits conversion bridge enabled.
(2) P = cam2_pclk period in ns
(3) Maximum cycle jitter supported by cam2_pclk input clock.
(4) The timing requirements are assured for the cycle jitter and duty cycle error conditions specified.
(5) n = 15 (Data bus size is limited to 8 bits. So the bits configuration is either cam2_d[7:0] or cam2_d[8:15]). Lines not connected must be
tied low. When the number of data lines is less than cam2_d[n:0], data lines can be connected to the upper or lower lines of
cam2_d[n:0]. Lines not connected must be tied low.
For more information about video port mapping, see the OMAP4470 TRM.
(6) See DM Operating Condition Addendum for OPP voltages.

(1) The polarity of cam2_pclk, cam2_fld, cam2_vs, and cam2_hs are software configurable. Optionally, the cam2_wen signal can be used
as an external memory write-enable signal. For further details, see the OMAP4470 TRM.
(2) N = 15 (Data bus size is limited to 8 bits. So the bits configuration is either cam2_d[7:0] or cam2_d[8:15]). Lines not connected must be
tied low. When the number of data lines is less than cam2_d[N:0], data lines can be connected to the upper or lower lines of
cam2_d[N:0]. Lines not connected must be tied low.
