Oscillator (OSCD)
There is a dedicated oscillator in the LatticeECP2/M devices whose output is made available for users. The oscilla-
tor frequency is programmable with a range of 2.5 to 130MHz. The output of the oscillator can also be routed as an
input clock to the clock tree. The oscillator frequency output can be further divided by internal logic (user logic) for
lower frequencies, if desired. The oscillator is powered down when not in use. The output of this oscillator is not a
precision clock. It is intended for use as an extra clock that does not require accurate clocking.
