MAX31D80

www.DataSheet4U.com 19-5214; Rev 0; 4/10 Spread-Spectrum Clock Generators 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-spectrum 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 MAX318C80/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 output frequencies (see the Ordering Information table). A low-cost, low-frequency crystal can be used at the input to generate frequencies up to 134MHz.
