Spread-Spectrum Clock Generators
MAX31C80/MAX31D80
General Description
The MAX31C80/MAX31D80 are spread-spectrum clock
generators that contain a phase-locked loop (PLL)
that generates a 2MHz to 134MHz clock from an input
clock or crystal. The PLL can provide a spread-spec-
trum down-dithered (MAX31D80) or center-dithered
(MAX31C80) frequency-modulated clock. The devices
also buffer the incoming clock and provide this output
on a separate pin.
The MAX31C80/MAX31D80 are provided in a 10-pin
TDFN package and operate over a full -40NC to +125NC
automotive temperature range. Devices can be factory
programmed for multiple combinations of input and out-
put frequencies (see the Ordering Information table). A
low-cost, low-frequency crystal can be used at the input
to generate frequencies up to 134MHz.
