Hi,

I am using LKMK03328 for clock source.

I need 3-125MHz LVDS

2- 156.25MHz CML

2-25MHz CML

1-100MHz CML clocks for my chips. I need hardware control Mode solution for this.

Hello Manish,
LMK03318 is another option if you don't have the need for a second PLL. Both devices have EEPROM that can be programmed.
For programming the device, refer to section 10.5 of datasheet.

Vicente

Output	Frequency	Type
OUT0	25 MHz	CML
OUT1	156.25 MHz	CML
OUT2	156.25 MHz	CML
OUT3	100 MHz	CML
OUT4	125 MHz	LVDS
OUT5	125 MHz	LVDS
OUT6	125 MHz	LVDS
OUT7	25 MHz	LVDS

Can I achieve above configuration with Hardware Control.

Or I will get only configuration that comes with Defaut EEPROM Image.

Hi Manish,
You can have these frequencies in the desired formats but they would be at different Outputs, not the ones you listed. It would be as follows:
You will not be able to achieve the above configuration with HW CNTRL. You will have to program the device.
