SP8854E - 27GHz Parallel Load Professional Synthesiser
These pins are the data inputs to set the RF divider ratio (MN1A).
High is open circuit on these pins.
Data is transparent from pins to RF buffer when pin 39 (STROBE) is high and frozen in buffers when pin 39 is low.
Balanced inputs to the RF preamplifier.
For single-ended operation the signal is AC
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 16bit words to set the RF and reference counters and the SP8855E which is fully programmable using hard wired
