SP8852E - 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).

SP8852E 2 7GHz Parallel Load Professional Synthesiser Preliminary Information Supersedes January 1996 version, DS4237 - 1.2 DS4237 - 2.0 June 1998 The SP8852E is one of a family of parallel load synthesisers containing all the elements apart from the loop amplifier to fabricate a PLL synthesis loop.
Other parts in the series are the SP8854E which has hard wired reference counter programming and requires only a single 16-bit programming word, and the SP8855E which is fully programmable using
