Spread Spectrum Clock Generators that support I2C configuration

Question: Which spread spectrum clock generators support I2C configuration?

 

Answer:

The clock generators with spread spectrum functionality supporting I2C for configuration are:

CY2545 - 4 PLLs, 8 outputs, VDD = 2.5V, 3.0V or 3.3V

CY2547 - 4 PLLs, 8 outputs, VDD = 1.8V

M200 - 2 PLLs, 3 outputs, VDD = 1.8V, low power

M300 - 3 PLLs, 3 outputs, VDD = 1.8V, low power

M600 - 3 PLLs, 3 outputs, VDD = 2.5V, 3.0V or 3.3V, low power

M4000 - 4 PLLs, 8 outputs, VDD = 1.8V, low power

M6000 - 3 PLLs, 8 outputs, VDD = 2.5V, 3.0V or 3.3V, low power

M8000 - 4 PLLs, 8 outputs, VDD = 2.5V, 3.0V or 3.3V, low power

The I2C interface is used to make changes to volatile configuration memory.  All I2C changes are lost when power is removed from the chip.  Devices can be programmed to power up in a pre-defined configuration.  Such programming is done before the devices are installed on a board.  Users may program devices themselves, employ the programming services of a distributor or third party, or if the quantities are sufficient, Cypress can provide pre-programmed devices as custom part numbers.
