PCIE CLOCK GENERATOR

Hello NXP Team

I have a query regarding PCIe clock generator used in 8MPLUS-BB Reference Board .

As per reference board to use internal clock, (When using internal clock populate R135, R136, remove R131, R132, R137, R138) , Have NXP validated reference board with internal clock (clock sources by iMX 8M plus processor to peripheral, without using pcie clock generator) , Is that solution working ?

Do Pcie Clock Generator necessary for iMX 8M plus ?

On EVK, a PCIE clock generator chip (9FGV0241) is used to feed high-quality clock to both the PHY and connecter/device. If a PCIE clock generator is not available, use the internal clock of the chip. Note that the internal clock exhibits larger jitter than that from PCIE clock generator.
