SP8852E - 1.7GHz PARALLEL LOAD PROFESSIONAL SYNTHESISER

Datasheet Summary

Description

These are the inputs to the 16-bit data bus.

When pin 38 is high the data goes to the buffers for the A counter, M counter and phase detector gain.

When pin 38 is low the data goes to the buffers for the reference counter and the phase detector state (see Table 4).

Features

  • s 2.
  • 7 GHz Operating Frequency s Single 5V Supply HC44 s Low Power Consumption.

SP8852E 2·7GHz Parallel Load Professional Synthesiser Preliminary Information Supersedes January 1996 version, DS4237 - 1.2 DS4237 - 2.0 June 1998 The SP8852E 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 SP8854E which has hard wired reference counter programming 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. Data can be stored in one of two internal buffers, selected by a single address bit on the input interface.
