OV6620 PCLK CLK

Hi,

I am using OV6620 Omnivision CMOS Image sensor. My module has CLK fosc: 17.734MHz PCLK: 112ns = 8.92MHz

Does any body know how this is acheieved (mathematically ?)

Thanks, Archilles

112 ns * 145 / 288 = 56+7/18 ns

112 ns --> 8.92857 MHz

56+7/18 ns --> 17.73399 MHz

You could do this with a phase-locked loop and two counters, one 8-bit and one 9-bit.
