Spread-Spectrum Clock Generators
MAX31C80/MAX31D80
6_ _ _______________________________________________________________________________________
Detailed Description
The MAX31C80/MAX31D80 modulate an input clock to
generate a center-dithered or down-dithered spread-
spectrum output. An 8MHz to 27MHz crystal or 8MHz
to 134MHz oscillator input is applied to the device. An
internal PLL dithers the output clock at a user-select-
able magnitude to produce a down-dithered or center-
dithered output clock. The output clock’s frequency is
programmable from 2MHz to 134MHz. The devices also
buffer the incoming clock and provide this output on a
separate pin.
Spread-Spectrum Dither Magnitude
The MAX31D80 can generate down-dithered magnitudes
up to -3%. The MAX31C80 can generate center-dithered
magnitudes up to P 1.5%. The desired magnitude is
selected using the input pins SMSEL1 and SMSEL0 as
shown in Tables 1 and 2. A power cycle is required after
each change of the dither magnitude for the changes to
take effect.
