OSCOUT signal cannot be guaranteed in such a configuration.
AC coupling of a single ended external clock to XTI, with OSCMODE = 1, is possible. It is recommended that the
circuit shown in Figure 15 be used to correctly bias the oscillator inputs: The common-mode voltage V
and XTO, (set by the 36 kΩ and 22 kΩ resistors) must be in the range 800 mV to CVdd and the amplitude Vpp of
the clock signal must be >100 mV. See Figure 15.
External, differential clock signals may be applied to XTI and XTO if OSCMODE = 1. The common-mode voltage V
for the differential clock signals must be in the range 800 mV to CVdd, and the peak-to-peak signal amplitude Vpp
must be >100 mV. It is recommended that differential clock signals have V
of ≥ 390 Ω in series with XTI or XTO may be required to limit the current taken from or supplied to the clock
sources.
