The 9FGV1008 is a member of Renesas' PhiClock™ programmable clock generator family. The 9FGV1008 provides one integer frequency, one copy of a fractional or spread spectrum output frequency, and one copy of the crystal reference input. Two select pins allow for hardware selection of the desired configuration, or two I2C bits allow easy software selection of the desired configuration. The user may configure any one of the four OTP configurations as the default when operating in I2C mode. Four unique I2C addresses are available, allowing easy I2C access to multiple components.
