APPLICATION NOTES
An application note, AN168, is available for designing with
synthesisers such as the SP5611. It covers aspects such as loop
filter design, decoupling and I
2
C bus radiation problems.
The application note is published in the Mitel Semiconductor
Media IC Handbook. A generic test/demonstration board has
been produced, which can be used for the SP5611. A circuit
diagram and layout for the board are shown in Figs. 8 and 9.
The board can be used for the following purposes:
(A) Measuring RF sensitivity perfomance
(B) Indicating port function
(C) Synthesising a voltage controlled oscillator
(D)Testing external reference sources
The programming codes relevant to these tests are given in
Table 6.
