Description:Provides 48 PCIe Gen2 lanes and 12 ports of high-performance, deterministic system interconnect switching. All ports receive full line rate, non-blocking throughput for multiple traffic flows regardless of switch loading.
Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
Renesas recommends a specific power sequencing scheme in their datasheet, which involves powering up the VCC and VDD pins in a specific order. Additionally, they provide a power sequencing diagram in their application note (APL-AN-1202).
Renesas recommends using high-frequency, low-ESR capacitors (e.g., 100nF, 1uF, and 10uF) with a voltage rating of 2.5V or higher, placed as close as possible to the power pins. The exact values and placement can be found in the datasheet and application notes.
Renesas provides a JTAG interface specification in their datasheet, which includes pinouts, signal levels, and protocol information. Additionally, they offer a JTAG programming guide (APL-AN-1203) that covers testing and programming procedures.
Renesas provides thermal design guidelines in their application note (APL-AN-1201), which include thermal resistance values, junction-to-case thermal resistance, and recommended thermal interface materials. Engineers should also consider using thermal simulation tools to optimize their design.
