... LVTTL input is a level sensitive strobe used to latch the USB_48/FS_A, FS_B, FS_C/TEST_SEL and PCIF0/ITP_EN inputs. After VTT_PWRGD# (active low) assertion, this pin becomes a real-time input for asserting power down (active high). I 14.318-MHz crystal input 14.318-MHz crystal output.

... Crystal Recommendations The CY28411-1 requires a Parallel Resonance Crystal. Substituting a series resonance crystal will cause the CY28411-1 to operate at the wrong frequency and violate the ppm specification. For most applications there is a 300-ppm frequency shift between series and parallel crystals due to incorrect loading. ...
