Requesting Help: Seiko Epson Crystal

I have inherited a design with a 25 MHz crystal, Seiko-Epson FA238. It is either:

SER3691CT-ND @ 18 PF
or
SER3692CT-ND @ 10 PF

The top of the device says:
2500P
E75T8

It feeds an Atheros AR8035 PHY. That datasheet does not specify crystal capacitance.

Can anyone help me identify which part I have?

Hello Larry,

Is there any way you can identify the parallel capacitors in the circuit? That may help. I gave the part marking to our Epson product manager and he requested the capacitors ID. Thanks.
