SP8854E - Zarlink Semiconductor

SP8854E 2.7GHz PARALLEL LOAD PROFESSIONAL SYNTHESISER

SP8854E 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-coupled into pin 13 with pin 14 AC-decoupled to g.
