TCAN4551-Q1: Input Capacitance OSC1 terminator (external OSC)

Tool/software:

Hello -

We are using the TCAN4551-Q1 with an external oscillator.  We have two pieces of the TCAN4551 in our design, and wondering if we can use the same oscillator to drive OSC1 clk input on both IC's.  The CMOS oscillator gives a max load capacitance of 15pF.  Do you have a spec for the input capacitance of the OSC1 terminal?

Thank you
