5 Description (continued)

The device supports nonvolatile EEPROM programming for easy customization of the device to the application.

All device settings are programmable through the I2C bus, a 2-wire serial interface.

The CDCE813-Q1 operates in a 1.8-V core environment as well as eliminating the need for additional,

independent XTAL oscillators which reduces component count and board size. It operates in a temperature

range of –40°C to 105°C.
