Is it possible to use I2S0 and I2S1 at different sample rates at the same time?

Hi,
I am working on a project that utilises a I2S audio input, and wish to make use of I2S output with FastLED for driving LED's.
I had configured my I2S0 as an input with 48khz sample rate, with I2S1 as an output at (i think) 8Mhz.
When I test my project using either 1 of these, it works fine, however when using both together I get a lot of unexpected data on the audio input.
Before digging into the code side of things I just wanted to check at the hardware level...
Can the I2S devices configured to work as independent devices or do they have a shared clock?
Thank you.
