SP8854E
2·7GHz Parallel Load Professional Synthesiser
Preliminary Information
Supersedes January 1996 version, DS4238 - 1.2
DS4238 - 2.0 June 1998
The SP8854E 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 SP8852E which is fully programmable, requiring tw0 16-
bit words to set the RF and reference counters and the
SP8855E which is fully programmable using hard wired links
or switches.
The SP8854E is programmed using a 16-bit parallel data
bus. Data is stored in an internal buffer. The 10-bit program-
mable reference divider is programmed by connecting the 10
programming pins either to ground or
1
5V. The device can
therefore be programmed with a single transfer from the
control microprocessor. Hard wired inputs can also control
the
F
PD
and F
REF
outputs and the control sense of the loop.
