Evaluation Board Setup Table 1. Inputs and Outputs Output Name(s) Input/Output Required? Function RFoutRx RFoutTx Output Required One of these outputs needs to be attached to phase noise measurement equipment, like the Agilent E5052. The unused output need not be connected. Vcc3p3 Input Required Connect to a 3.3 V Power Supply. Ensure the current limit is set above 100 mA. Vcc5V Vcc5VTV_TB Input Optional Instead of using the Vcc3p3 connector, one can connect 5V to one of these outputs and it is regulated down to 3.3V on the board. Programming Interface Input Required Connect the board to a PC using the USB2ANY (HPA665-001) interface provided in kit. OSCin Input Optional The on-board 20 MHz XO has been enabled. To use this input, the XO power supply resistor (R1) should be removed and resistor R3 moved to position R2.

In order to readback, this needs to be done with external software. As a means of debugging, consider using the power down feature and monitoring the changes in the current consumption. 1.5 Lock Detect Notification The lock detect on the LMX2571 works perfectly well. However, the LED decides to light when it feels like it. Pressing on the LED with one's fingernail can sometimes get it to work better. The key takeaway from this is the green LED is not reliable for lock detect. If it is on, it indicates lock, but if it is off, it indicates unlock or an issue with the LED diode. 1.6 Pin 8 Component Notification Note that Pin 8 has a capacitor to ground, but it was found that this component provided no benefit, although it does no harm either. 4 LMX2571EVM User's Guide SNAU176A – January 2015 – Revised June 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Setup www.ti.com 1.7 Crystal Oscillator Noise Notification The following plot shows the XO noise compared to a much cleaner reference. The XO is included for quick startup and evaluation, but can be bypassed or changed. The criteria for choosing the XO was availability and standard footprint, which took priority over phase noise and stability. Sometimes if the XO is burn in by letting the board run for a few hours, the phase noise and stability will improve. Optimal phase noise is obtained with a clean input signal. Figure 2.
