LMK05028: LMK05028 HARD PIN MODE

Hi Merve,

In ROM mode, HW_SW_CTRL = 1 and GPIO[3:0] state is used for selecting ROM page number. ROM configs are different from EEPROM configuration.

What is the state of GPIO[3:0] at the input?

-Riley

What frequency and OUT# that you're reading frequency that is different? I assume you compared to EEPROM output, correct?

-Riley

GPIO0:1 GPIO1:0 GPIO2:0 GPIO3:0 

OUT0:  122 MHZ OUT1:122 MHZ OUT3: 122 MHZ OUT4:322 MHZ

Hi Riley ,

Could you help me?

Hi Merve,

We don't have ROM pages exposed. Are you using the EVM with onboard XO 48 MHz?

-Riley

Hi Riley,

We have not used EVM. But we have used XO(48.0048 MHz) in EVM.  

My question is simply this: If I use the LMK05028 in Hardpin mode, what will happen to the OUT# frequencies?

Is EEPROM the same as default mode?

Thank you for your help.
