Re: ADV212 question

When ADV212 is used in the still image compression, the input mode is the single-component input, ADV212 HIPI mode, the image width is 4096 pixels, each pixel 10bit, 128 is a line of the image frame, 4096 * 128 is sent to a  ADV212, in this case ADV212 works. However, other conditions are the same, just change each pixel 8bit, 4096 * 128 is sent  to  a ADV212, I change parameter settings, PMODE1 REGISTER is changed from 0x”0118”  to 0x "0014", ADV212 Firmware Parameter Encode Settings in PREC setting from "1" to "0", in addition, ADV212 parameter settings are the same, but ADV212 doesn’t work properly,When I change  MCLK and VCLKfrom 25MHz to  30MHz, ADV212 works, this time PLL_HI set 0X0008, PLL_LO set 0X0006, so JCLK equal to 30MHz * 6 = 180MHz, the maximum value exceeds the manual 150MHz.To make ADV212 normal compression 4096 * 128 (each pixel 8bit), how can I do?

Using 5/ 3 wavelet, I have tried width 4096 pixel still images , each pixel 10bit, 128 lines each are sent to a  ADV212 , ADV212 works properly ; width 4096 pixel still images , each pixel 10bit,  every 256 lines given to  a ADV212, also can work properly, so much more than manual 5/3 wavelet support for tiles up to 262,144 samples.Can ADV212 compress 4096 * 128 or 4096 * 256 ( each pixel 10bit ) properly?
