LMK5C33216: Disable output command

Zhizhao Niu

Part Number: LMK5C33216

Hi Team,

I want to disable the OUT14 LVDS output. When I using the TICS pro to check the command and I have below questions:

1. Why 0x4E2 will be written twice?

2. Why 0x361 will rewrite the default value.

Thanks.

Hello Zhizhao,

When TICS Pro does writes during changes, it may do them field-by-field, so sometimes you'll see multiple writes and you only need to do the last.

The 0x361 is not required as it is not changing. This is related to PLL3 and shouldn't be in the list. I will investigate why it is being listed.

Hi Timothy,

Thanks for your help. May I know is there any updates? And add one more question:

1. If I want to update it into EEPROM and just want to disable out14. I think what I should do is write 0x4E2 to 4F, right?

Thanks.

Hi Zhizhao,

I don't have an update at this time. However as for your disable question. Write 0x4e0 = 0x28, this changes the OUT_14_FMT from LVDS to DISABLED.
