EEPROM selection for ADAU1701

The clock speed from ADAU1701 to the EEPROM is specified in the datasheet as:

 

The ADAU1701 generates SCL at 8 × fS; therefore, for a fS of 48 kHz, SCL runs at 384 kHz.

 

I'm planning to use a fs of 96 kHz and from above I should expect SCL to get doubled to 768 kHz. The number of available EEPROM devices get very restricted since most are specified to use max 400 kHz. On the evaluation board for the 1701 there is a std EEPROM and to me it works ok although I haven't been able to measure the actual SCL clock frequency.

 

What EEPROM speed should be used with fs=96 kHz to feel safe?
