SP8852 27GHz Parallel Load Professional Synthesiser

SP8852 27GHz Parallel Load Professional Synthesiser

These are the inputs to the 16-bit data bus. When pin 38 is high the data goes to the buffers for the A counter, M counter and phase detector gain. When pin 38 is low the data goes to the buffers for the reference counter and the phase detector state (see Table 4). Open circuit = 1 (high) on these p.
