Lattice Semiconductor
PCLK PIO (Primary Clock Pads)
There are two PCLK PIOs on top and two PIOs on bottom, for a total of four pins for each MachXO device. These
pads connect directly to the global clock network.
PLL PIO
There are two pad pairs (one pad pair on the upper side and one pair on the lower side) for the MachXO2280 and
one pad pair for the MachXO1200.
PLLFB PIO
Two pad pairs (one pad pair on the upper side and one pair on the lower side) for the MachXO2280 and one pad
pair for the MachXO1200.
Primary Clock Mux Connectivity
The Primary Clock Mux input sources include:
• Primary clock input pins.
• PLL outputs
• From routing
The Primary Clock Mux outputs feed four clock input switch boxes in a PFU.
