2.8GHz Parallel Load Professional Synthesiser

Advance Information

DS4239

ISSUE 3.0

PIN 1

March 1999

The SP8855E 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 devices in

the series are the SP8852E which is a fully programmable

device requiring two 16 bit words to set the RF and reference

counters, and the SP8854E which has hard wired reference

counter programming and requires a single bit word to pro-

gram the RF divider. The SP8855E replaces the existing

SP8855D.

The SP8855E is intended for applications where a fixed

synthesiserfrequencyisrequiredalthoughitcanalsobeused

where frequency selection is set by switches. In general the

device will be programmed by connecting the programming

pins to either V_CCor ground. Additional hard wired inputs can

HC44

be used to control the F_pdand F_refoutputs set the control

direction of the loop and select the phase detector gain.

Another input may be used to disable the phase detector

output.

The device is available in both plastic (HP) and ceramic

(HC) J-leaded 44-lead chip carrier. Ambient temperature

ranges available are shown in the ordering information.
