Spread-Spectrum Crystal Multiplier
3Maxim Integrated
Note 1: All voltages referenced to ground.
Note 2: Maximum source/sink current applied to input to be considered an open. Typical voltage range between 0.4 x V
CC
and
0.55 x V
CC
.
Note 3: Applicable to pins CMSEL, SMSEL, and PDN.
Note 4:
See information about C
L1
and C
L2
in the Applications Information section at the end of the data sheet.
Note 5: Not production tested.
Note 6: For 7pF load.
Note 7: Time between PDN deasserted to output active.
Note 8: Time between PDN asserted to output high impedance.
Note 9: Guaranteed by design.
