Setup

2.2 Power Supply

Apply 3.3 V to VCCSMA connector. Acceptable supply voltage range is 3 V to 3.6 V. The maximum current consumption in the most extreme configuration must not exceed 150 mA.

By default, the onboard DC-DC converter is not used.

2.3 Reference Clock

Connect OSCinP SMA connector with one of the outputs from Reference PRO using the SMA Male-tomale adopter. OSCinM SMA connector is not connected to LMX2572 so it could be left open.

The EVM is configured for single-ended input with OSCin pin connected to OSCinP SMA connector and OSCinM pin 50-Ω terminated onboard. If required, the EVM can be modified to operate with different clock source in different configuration, see Appendix A for details.

Terminate the unused output of the Reference PRO board with a 50-Ω resistor or SMA load. By default, the output clock from Reference PRO is a 100-MHz LVPECL clock. Appendix B has the details of Reference PRO.

2.4 RF Output

Connect either RFoutAP or RFoutAM SMA connector to a signal analyzer. The unused connector must be terminated with a 50-Ω resistor or SMA load. Output frequency is 3 GHz and the amplitude is about +2.5 dBm.

By default, the evaluation software, TICS Pro, has RFoutB power down. These SMA connectors could be left open.

www.ti.com

2.5 Programming

Connect ribbon cable from Reference PRO to LMX2572EVM. Connect USB cable from a PC to USB port in Reference PRO. This provides power supply to Reference

PRO board and communication with TICS Pro. A firmware update may be required, see Appendix B for details.

2.6 Evaluation Software

Download and install TICS Pro to a PC. Run the software and follow the following steps to get started.

1. Go to "Select Device" → "PLL + VCO" → LMX2572.

3.2.1 Phase Adjustment

The phase of the RF output signal can be adjusted as follows: Phase shift in degree = 360° × (MASH_SEED / PLL_DEN) × (P / CHDIV), where P = 2 when

VCO_PHASE_SYNC_EN = 1, else P = 1. Here is an example.

3.2.2 Calibration-free Automatic Ramping

LMX2572 supports linear frequency ramp without the need of VCO calibration in the middle of the ramp. The output waveform is a continuous frequency sweep between the start and the end frequencies. However, the frequency ramp range is limited. When using ramp, the followings need to be set accordingly:

• OUT_FORCE = 1

• LD_DLY = 0

• PLL_DEN = 232– 1

Typical Measurement

This is a triangular ramp example. Ramp up is defined by RAMP0 while ramp down is defined by RAMP1. RAMP_THRESH, RAMP_DLY_CNT, and RAMP_SCALE_COUNT are "don't care" because we are not going to trigger any VCO calibration. RAMP_MANUAL = 0 means Automatic Ramping mode.

Set RAMP_EN = 1 to start ramping. Set RAMP_EN = 0 to turn off ramping.

3.2.4 SYSREF Example

RFoutB of LMX2572 can be used to generate or duplicate SYSREF signal. The output of RFoutB can be a single pulse, series of pulse, or a continuous stream of pulses. These pulses are synchronous with the RFoutA signal with an adjustable delay. To use the SYSREF capability, the PLL must be in SYNC mode with VCO_PHASE_SYNC_EN = 1. Here is an example of Pulsed mode.

Reference PRO

The Reference PRO board is used to program the LMX2572EVM and at the same time, provide a clean reference clock to LMX2572EVM. The board has several control pins dedicated for control of output format, output frequency, and output enable control. These control pins are configurable through the jumpers by strapping the center pin to Vdd position or GND position. Connections from the Vdd position to the device supply or from the GND position to the ground plane are connected by 1.5-kΩ resistors. By default, the board is configured for 100-MHz LVPECL output. The power supply to Reference PRO is obtained from the PC that is connecting to Reference PRO through the USB interface.
