LMX2485SQ/NOPB Frequently Asked Questions (FAQ)
-
A good PCB layout for the LMX2485SQ/NOPB involves separating the analog and digital grounds, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated layer for the analog ground and another for the digital ground.
-
To ensure proper bypassing, use a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed as close as possible to the device's power pins. Additionally, use a 1uF ceramic capacitor on the analog supply pin (VCCA) and a 1uF ceramic capacitor on the digital supply pin (VCCD).
-
A high-quality clock source, such as a crystal oscillator or a low-jitter clock generator, is recommended. To ensure clock signal integrity, use a clock signal with a frequency of 10MHz to 30MHz, and ensure the clock signal is routed as a differential pair to minimize noise and jitter.
-
To optimize phase noise performance, set the device to the 'Low Noise' mode by setting the LN bit in the control register. Additionally, ensure the device is operated within the recommended voltage range (2.7V to 3.6V) and temperature range (-40°C to 85°C).
-
The recommended settings for the internal PLL depend on the specific application. However, as a general guideline, set the PLL loop bandwidth to 100kHz to 500kHz, and the PLL damping factor to 0.5 to 1.5. To ensure PLL lock, monitor the PLL lock detect output (LD) and adjust the PLL settings as needed.
