Overview
Description
The 9FGV1005 is a member of Renesas' PhiClock™ programmable clock generator family. The 9FGV1005 provides two copies of a single non-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 all 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.
