microchip

This IC generates a 25MHz sinusoidal waveform centered at 2.55V with an amplitude of 0.85V (Vpp = 1.7V) when given a 12-bit binary input that count from 000h through FFFh with transitions occuring at 50MHz. The major design blocks include a 12-bit Accumulator, 8-bit ROM Pointer, 4x64-bit ROM and a 10-bit DAC. See schematic in Figure 2 in the project report.
