9.2.2 Detailed Design Procedure

The LMK6x has three different options for differential output which are LVDS, LVPECL, HCSL type and one LVCMOS single-ended output type. For designing with the any of the oscillator output type in actual system, use the proper AC or DC termination based on the application requirement. Refer to the Clock Output Interfacing and Termination section for the details of all the AC and DC termination schemes and use the appropriate option. The figures in this section have all the AC and DC coupling options with the termination resistor values. The LMK6x has an integrated LDO and has excellent PSRR performance as shown in the Electrical Characteristics table. Refer to the LMK6EVM for the reference layout recommendation while designing the LMK6x BAW oscillator.

For the Function Pin 1 of LMK6C, connect typical 10-kΩ or less resistor to VDD for driving the OE pin High. Note this pin can be left open if you do not want to use pullup resistor as the device has > 100-kΩ internal pullup resistor. For driving the OE pin to Low, use the typical 10 kΩ or less resistor as a pulldown resistor. For the Function Pin 1 or Functional Pin 2 for LMK6D, LMK6H, LMK6P, you can use the similar approach described for LMK6C.
