SL11RIDE USB Transceiver Characteristics
Notes:
10. All typical values are VDD2 = 3.3 V and TAMB= 25°C.
11. ZUSBX Impedance Values includes an external resistor of 24 -- 43 Ohms ± 1%

SL11RIDE Reset Timing
The nRESET signal from the SL11RIDE chip resets the disk drive. It forces an initialization to occur identical to that after power-up.
