... The four downstream ports support both full-speed (12-Mbps signaling rate) and low-speed (1.5-Mbps signaling rate) devices. The CY7C65100 sereis has a reduced frequency (6- MHz) crystal oscillator for lower system cost as well as improved EMI performance. The four-port CY7C65100 series is available in a cost-effective and space-saving 28-lead SOIC package. ...

... Clocking XTALIN and XTALOUT are the clock pins to the CY7C65100 series. The user can connect either an external oscillator or a crystal to these pins. A 6-MHz fundamental crystal can be connected to these pins to provide a reference frequency for the internal PLL. When using an external crystal, keep PCB traces between the chip leads and crystal as short as possible (less than 2 cm). A ceramic resonator is not an adequate clock source to meet the timing specifications of a high-speed USB function and therefore cannot be used with these parts ...

... The power switching and over-current detection of downstream ports is managed by control pins connected to an external power switch device (see Figure 6-1). The active-LOW PWR[n] output pins of the CY7C65100 series are connected to the respective external power switch’s port power enable signals. (Note that each port power output pin of the external power switch must be bypassed with an electrolytic or tantalum capacitor as required by the USB specification ...
