(refer to the usb specification section 7.1.1.1). since the CM2400-01 output impedance is about 6 ? , it is recommended that 33 ? series resistors be used. figure 10. schematic for usb peripheral device the mode pin selects the differential receiver mode when high (cmos level or v cc ), and selects the single-ended receiver mode when low (con- nected to gnd). the CM2400-01 is used in bus-powered systems only, where the v bus supply pin is connected to the +5v v bus line from the usb connector. the v cc supply pin is the supply for the i/o signal logic that provide the interface with the asic. the v cc supply must range between 1.65v min and 3.6v max.
