CPLD programmable logic / Oscillator for Lattice CPLD dev board
Hi,

I'm going to do a free PCB build of the Lattice CPLD dev board v1. It looks like a nice little chip and I'm going for the LC4032V-25TN44C variant. I can figure out most parts from the board parts list/master parts list but I'm unsure what frequency the oscillator should supply? I can't find anything about external oscillators in the datasheet. From Ian's schematics the osc is connected via a solder-jumper, so it must be optional. Any advice/explanation is welcome. Thanks!
