Default Help Needed to Read Filter Chip (YM3414) Datasheet

I'm trying to use the YM3414 for a 44.1 kHz asynchronous I2S input. Can this be accomplished by connecting SyncS (pin 15) to X1 (pin 3) so that it receives the same clock signal from the 16.9 MHz (384 fs) oscillator?

Page 6 on the datasheet is where I got the idea. It seems that synchronous inputs require SyncS to be a constant L, but asynchronous inputs appear to require an oscillating SyncS.

The datasheet is attached.

Oops, that would be a constant H for synchronous inputs.

So does SyncS need to be oscillating for asynchronous input or a constant L?
