TEENSY 3.5 SPI Bus SPEED?

[GOHO]

Hi, Can anyone tell me what the max SPI Bus speed is on the TEENSY 3.5? I want to interface with an LTC2315 - 12 5 msps ADC but i need a 100 mhz SPI bus i believe to accomplish that speed so i want to verify that the Teensy 3.5 could read at that speed?.

SPI runs at F_BUS/2 max. For Teensy 3.5 F_BUS is typically 60 mhz. There are threads discussing how you might overclock and get 120mhz F_BUS by modifying hardware/teensy/avr/cores/teensy3/kinetis.h. I doubt you can reach 100 mhz SPI. You'll need to have very short circuit paths (PCB?) for such high frequencies.
