Low Phase-Noise, Low-Power
Programmable PhiClock™ Generator
9FGV1006
Datasheet
Description
The 9FGV1006 is a member of IDT's PhiClock™ programmable
clock generator family. The 9FGV1006 provides two copies of a
single integer, 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 I
2
C 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 I
2
C mode. Four unique I
2
C addresses
are available, allowing easy I
2
C access to multiple components.
