Hi,
I was wanting to shift a 40Mbps datastream out a dsPIC30/33, clock is not required. I was thinking of using either a) SPI @40MHz, or b) 2x SPI@20MHz using SCLK to MUX the data into single 40MHz stream. I don't need the clock or receive lines externally otherwise.
The datasheets for the dsPICs I looked at specify a maximum 10MHz SCLK frequency. Does anyone know why this is? Or whether it will still function? I was guessing received data may become corrupt at the higher frequencies, or the output driver current consumption might increase...
Any info anyone has on operating the dsPIC SPI at these higher frequencies would be most welcome.
Thanks!
