NOTE:

Disconnect the power and signal paths from any XO circuit that is not used for a given

configuration to avoid unwanted spurious noise on the board. Y1 can be powered down by
JP17 (Tie pins 2-3). U10 can be powered down by JP21 (Tie pins 2-3).

Figure 5. XO Input Interface (1 of 2) - 48.0048-MHz Oscillator and SMA Ports

3.3.3

LMK61E2 Programmable Oscillator

The last option is to use the other onboard LMK61E2 programmable oscillator (U10) to drive the XO_P/N
inputs. See

.

The differential output clock from U10 can be routed to the XO_P/N input pins with minimal rework by
placing 0.1-µF capacitors on C137 and C138, and opening C80, C81, and C82 (note: C137 shares a pad
with C80 and C81, and C138 shares a pad with C82). U10 can be powered by a clean 3.3-V supply from
LDO3 by tying JP21 pins 1-2.
