ELECTRICAL CHARACTERISTICS, 48MHZ, USB

Following Conditions Apply Unless Otherwise Specified:

Operating Condition: TA = 0°C to +70°C, Supply Voltage: VDD = 3.3V ± 5%; CL = 10 - 20pF

NOTES:

1.

This parameter is guaranteed by design, but not 100% production tested.

2.

All long term accuracy and clock period specifications are guaranteed with the assumption that the REF output is at 14.31818MHz.
