24.12.2 USB High Speed Source Electrical Characteristics
MC68HC908LD64
Freescale Semiconductor
Notes:
Internal operating frequency
Transition time
Rise/Fall time matching
Output signal crossover voltage
High speed data rate
Frame interval
Source differential driver jitter
Source EOP Width
Differential to EOP transition skew
Receive data jitter tolerance
Receiver EOP width
1. All voltages measured from local ground, unless otherwise specified. All timings use a capacitive load of 50pF, unless
2. Transitions are measured from 10% to 90% of the data signal. The rising and falling edges should be smoothly transitioning
3. Timing differences between the differential data signals.
4. Measured at crossover point of differential data signals.
