The recommended operating temperature range for the PCI1520IZHK is -40°C to 85°C, with a junction temperature of up to 125°C.
The PCI1520IZHK can be configured for different PCIe generations using the CFG_RATE pin. For Gen1, tie CFG_RATE to GND. For Gen2, tie CFG_RATE to VCC. For Gen3, leave CFG_RATE floating.
The maximum power consumption of the PCI1520IZHK is 1.5 W, with a typical power consumption of 1.2 W.
To implement SSC, connect the SSC_EN pin to VCC and adjust the SSC_FREQ pin to set the desired spread spectrum frequency.
Texas Instruments recommends following the PCIe specification for layout and routing, with careful attention to signal integrity, impedance matching, and decoupling.
