• Manufacturer Part Number: USB97C100
• Description: USB97C100 Multi-endpoint Usb Peripheral Controller(not Recommended For Designs)
• Manufacturer: Standard Microsystems Corporation

Note 1: All voltages are measured from the local ground potential, unless otherwise specified.
Note 2: All timing use a capacitive load (CL) to ground of 50pF, unless otherwise specified.
Note 3: Full speed timings have a 1.5K
Note 4: Measured from 10% to 90% of the data signals.
Note 5: The rising and falling edges should be smoothly transiting (monotonic).
Note 6: Timing differences between the differential data signals.
Note 7: Measured at crossover point of differential data signals.
Note 8: These are relative to the 24 MHz crystal.
