For a layout example of the LMK6Bx and bypass capacitor and AC-coupling capacitor value recommendations, refer to Section 9.5.2. See Section 8.3.4 for output type termination and biasing. Refer to the The LMK6B: Revolutionizing Optical Module Performance with Industry-Leading Ultra-Low Jitter BAW Oscillators application note to understand the benefits of the LMK6Bx for optical transceivers module applications.
