Texas Instruments provides a recommended PCB layout and thermal management guide in the application note SLUA623, which includes guidelines for thermal pad connection, PCB layer stackup, and heat sink design.
To configure the PCI1520IGHKEP for PCIe Gen3 mode, set the GEN3_EN pin high and ensure the device is powered from a 3.3V supply. Additionally, the device must be configured using the PCIe configuration space registers, as described in the datasheet.
The PCI1520IGHKEP supports cable lengths up to 7 meters at Gen1 speed, 3 meters at Gen2 speed, and 1 meter at Gen3 speed, assuming a high-quality cable with proper shielding and termination.
The PCI1520IGHKEP has built-in hot plug detection and power management capabilities. Use the HPD_PIN and PWREN_PIN to detect hot plug events and control power to the device. Refer to the datasheet and application notes for implementation details.
Texas Instruments recommends using ESD protection devices such as the TPD4E05U06 or TPD4S014, and filtering components like the 100nF capacitors and 22Ω resistors, as described in the datasheet and application notes.
