Texas Instruments provides a recommended PCB layout in the XIO2213BZAJ datasheet, but it's essential to follow good PCB design practices, such as keeping the signal traces short, using a solid ground plane, and minimizing noise coupling. Additionally, ensure the device is placed near the connector to reduce signal loss.
The XIO2213BZAJ requires a specific power sequencing to prevent damage. Apply VCC first, followed by V3P3, and then V1P8. Ensure that VCC is stable before applying V3P3 and V1P8. Also, ensure that the power supplies are ramped up slowly to prevent inrush currents.
The maximum cable length supported by the XIO2213BZAJ depends on the specific application and the type of cable used. As a general guideline, Texas Instruments recommends keeping the cable length below 1 meter for optimal performance. However, longer cable lengths can be used with proper signal conditioning and termination.
The XIO2213BZAJ can be configured for SATA or PCIe mode through the use of external resistors and straps. For SATA mode, connect the SATA_MODE pin to VCC, and for PCIe mode, connect it to GND. Additionally, ensure that the correct clock frequency is selected using the CLK_SEL pins.
The recommended clock frequency for the XIO2213BZAJ depends on the specific application. For SATA mode, a 25 MHz clock is recommended, while for PCIe mode, a 100 MHz clock is recommended. Ensure that the clock frequency is within the specified range to ensure proper device operation.
