When I use the setting of adv7612 as follow:

98 00 01 ; SD 1*625I

98 01 05 ; Prim_Mode =101 b HDMI-COMP ,50HZ

98 02 F5 ; Auto CSC, YCrCb out, Set op_656 bit

98 03 00 ; 8 bit 656

98 04 42;

98 05 2C ; AV Codes On

98 0B 44 ; Power up part

98 0C 42 ; Power up part

98 15 80 ; Disable Tristate of Pins

98 19 C3 ; LLC DLL phase

98 33 40 ; LLC DLL enable

I can get 27M CLK  at pin of PCLK, But I buy some new adv7612 this week, these setting can not get 27M CLK, When I set 01 as 06, I can get 25.3xx MHZ, The distributor tell me these adv7612 chips is new version in 2012.so I don't know difference of verison about adv7612.
