Max SPI Slave Clock Frequency?

[Jackie]

Any idea what the max SPI slave clock frequency is on the nRF51822? The product specification (page 46, v2.0) says the max SCK frequency is 2MHz, but I was wondering if any of you were able to go faster than this reliably. 2MHz is the bare minimum frequency I'd need, but it'd be better to go faster, so I thought I'd check before ordering an eval kit.

Thanks!

Hi Jackie,

You cannot go faster and still be within spec for the SPIS module. If you can go with 2MHz, then I would recommend that you do that, as many factors comes into play if you up the speed, like timing requirements and setup/hold times.
