8.4 Device Functional Modes

The LMK6x BAW Oscillator is a fixed output frequency device and does not require any programming. The

device pin 1 (and pin 2 for a 6-pin device) has different functions. See the Function Pins section for more

information on the function pins.

9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The LMK6x is high-performance, fixed-frequency oscillator that can be used as a reference clock. The product

family supports any output frequency between 1MHz to 400MHz for differential LMK6D, LMK6H, LMK6P or

1MHz to 200MHz for singled-ended LVCMOS clock output types, and 1.8V or 2.5V through 3.3V supply rails.

9.2 Typical Application

For reference schematic implementation for LMK6x family of oscillators, refer to the LMK6EVM User's Guide for

bypass capacitor and AC-coupling capacitor value recommendations. Refer to the Clock Output Interfacing and

Termination section for output clock required termination and biasing.

Figure 9-1 shows a typical application example. The LMK6D differential oscillator is used as an input to the

LVDS buffer input in this example.
