Broadcom provides a recommended PCB layout and thermal management guide in their application note AN2153, which includes guidelines for thermal pad connection, PCB layer stackup, and component placement to ensure optimal performance and thermal dissipation.
Calibration of the ADNS-6090 involves adjusting the sensor's gain and offset settings to match the specific optical and mechanical characteristics of the mouse or tracking system. Broadcom provides a calibration guide in their application note AN2154, which includes step-by-step instructions and recommended calibration procedures.
The ADNS-6090 is specified to operate over a temperature range of -20°C to 70°C, but it can be operated up to 85°C with reduced performance and accuracy. It's essential to ensure proper thermal management and cooling to maintain optimal performance and reliability.
The ADNS-6090's high-speed clock signal requires careful PCB design and layout to ensure signal integrity and minimize noise and jitter. Broadcom recommends using a differential clock signal, impedance-matched transmission lines, and proper termination to ensure reliable operation.
Broadcom recommends a specific power-up and power-down sequence to ensure proper initialization and shutdown of the ADNS-6090. This includes powering up the VDD supply before the VDDIO supply, and powering down the VDDIO supply before the VDD supply to prevent damage or malfunction.
