LMK01801: Input Clock Divider Value Range

Part Number: LMK01801

The 2019 revision of the datasheet shows a divide value of 1 in Table 7-31 yet Functional Block Diagram 1.4 shows only values of 2-8 allowable.  I have been using a divide setting of 1 and still getting a divide by 2 as was shown in the previous revision of the datasheet.

Is the new datasheet incorrect? Can the input clock divider actually be set to a implement a divide value of 1 without the explicit bypass circuit?

  • The updated datasheet is correct. The divider with value 2-8 is the CLKinX divider, not the CLKoutX_Y_Div of table 7-31. CLKoutX_Y_Div correspond to CG1 / CG2 / CG3 divider in Functional Block Diagram 1.4 .

    Kind regards,
