Hi,

Our customer confirmed the pin descriptions of LMK04826 datasheet.

・SYNC/SYSREF_REQ(6) = I/O 、OSCout,OSCout*(40,41pin) = O

Are these typo ? We believe SYNC/SYSREF_REQ(6) = I and OSCout,OSCout*(40,41pin) = I/O.

Best Regards,

Hi Kato-san,

These are correct in the DS. SYNC/SYSREF_REQ can be used as a SYNC input or as a programmable status pin depending on the application. OSCout/OSCout* are a buffered ouput of OSCin/OSCin* with programmable output types.

Hi Gabe - san,

Thank you for the reply. That means 6pin is Input-Output and 40,41pins are Output.

How is 6 pin used as Output ?

Regarding 40 and 41 pins, Could they be used CLKin2 as Input ?

Best Regards,

Kato

Hi Kato-san,

I must have overlooked that. Yes, pins 40/41 can either be OSCout/OSCout* or CLKin2/CLKin2* (OSCout functionality must be turned off). Additionally CLKin2_EN must be set.

I have checked with design and I am sorry for misinforming you. SYNC/SYSREF_REQ is an input only. I will note this change in the DS to properly reflect the device functionality.

Hi Gabe - san,

Please let me know when the revised edition DS will be released.In addition, please check whether other pin's I/O are correct.
