Context Before
It may surprise readers that Qualcomm has IP in the Groq LPU 3 chip! More specifically it is AlphaWave, which Qualcomm acquired last year, that is providing the 112G SerDes for Groq’s C2C. AlphaWave was selected as the only IP provider that has high speed SerDes for Samsung Foundry. It was AlphaWave’s SerDes that caused issues for Groq LPU 2. Alphawave will continue to be used for the LP35, but Nvidia will of course use their own NVLink SerDes IP from LP40 when it transitions back to TSMC.

Evidence
Of course, there are several other PCB modules in the compute tray, but they do not need a high spec
Context After
Cables and Connectors: Amphenol Continues to Benefit
For the LPX, Amphenol will be a beneficiary for all the connectors for the backplane. Each LPX node requires 16 80DP Paladin connectors for the backplane. There are also board to board connectors required to connect all the various modules within the tray: the main LPU board with the host CPU module and the OSFP/QSFP modules that sit below the CPU module, the front-end NIC module, and the management module. Amphenol will supply the cable backplane too which is 8,160 DP per rack.
