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 pro-
gramming and requires only a single 16-bit programming
word, and the SP8855E which is fully programmable using
hard wired links or switches.
The SP8852E is programmed using a 16-bit parallel data
bus. Data can be stored in one of two internal buffers, selected
by a single address bit on the input interface. In order to fully
program the device, two 16-bit words are required, one to
select the RF division ratio (A and M counters) and phase
detector gain, and one to set the 10-bit reference divider
count, phase detector state and sense. Once the reference
divide ratio has been set, frequency changes can be made by
a single 16-bit data load entry to the RF divider chain.
*FPD and FREF outputs are reversed by the phase
detector sense bit in the F1/F2 programming word, bit
12. The above diagram is correct when bit 12 is high.
