Description

The 8427-02 is a general purpose, six LVHSTL output high frequency synthesizer and a member of the family of High Performance Clock Solutions from IDT. The 8427-02 can support a very wide output frequency range of 15.625MHz to 500MHz. The device powers up at a default output frequency of 200MHz with a 16.6667MHz crystal interface, and the frequency can then be changed using the serial programming interface to change the M feedback divider and N output divider. Frequency steps as small as 125kHz can be achieved using a 16.6667MHz crystal and the output divider set for divide-by 16. The low jitter and frequency range of the 8427-02 make it an ideal clock generator for most clock tree applications.
