SP8852E  
2·7GHz Parallel Load Professional Synthesiser  
Preliminary Information  
Supersedes January 1996 version, DS4237 - 1.2  
DS4237 - 2.0 June 1998  
TheSP8852Eisoneofafamilyofparallelloadsynthesisers  
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. Datacanbestoredinoneoftwointernalbuffers, 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.
