ADS1293: Crystal or External Oscillator

Part Number: ADS1293

Hi,

I'm in the process of desinging a PCB with the ADS1293 and according the datasheet, either an external clock or the internal oscillator can be used.

The internal oscillator needs a Quarz, running at around 4.096MHz. The problem there is, that these Quarz are all pretty large (11mm long and even bigger) and for our application, space is crucial. So I thought first to use an external oscillator, but these seem to be very rare at around 0.4096MHz. So do I oversee anything here?
