Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'DS90UB914QSQX PCB Layout Guidelines' application note (SLUA623).
To ensure signal integrity, follow the guidelines in the 'DS90UB914QSQX Signal Integrity' application note (SLUA624). This includes using a solid ground plane, minimizing trace lengths, and using impedance-controlled traces.
The maximum cable length supported by the DS90UB914QSQX/NOPB is 10 meters (33 feet) at a data rate of 1 Gbps. However, this can be extended to 15 meters (49 feet) at a data rate of 500 Mbps.
The DS90UB914QSQX/NOPB can be configured for different data rates using the SPI interface. The device supports data rates from 100 Mbps to 1 Gbps, and the configuration is done using the 'DS90UB914QSQX Configuration and Programming Guide' (SLUA625).
The power consumption of the DS90UB914QSQX/NOPB varies depending on the data rate and operating mode. The typical power consumption is around 350 mW at 1 Gbps, and around 200 mW at 500 Mbps.
