8 / 12 page 8 SP5669 DOUBLE CONVERSION TUNER SYSTEMS The high 2.7GHz maximum operating frequency and excellent noise characteristics of the SP5669 enables the construction of double conversion high IF tuners. A typical system shown in Fig.8 will use the SP5669 as the first LO control for full band upconversion to an IF of greater than 1GHz. The wide range of reference division ratios allows the SP5669 to be used both for the up converter LO with a high phase comparator frequency (hence low phase noise) and the down converter which utilises the device in a lower comparison frequency mode (which offers a fine step size). 50–900MHz 1.6GHz 38.9MHz 1650–2700MHz SP5659 SP5659 First LO Second LO Reference Clock Fig. 8 Example of double conversion from VHF/UHF frequencies to TV IF CONTROL MICRO 15nF 68pF +30V +5V 22k 16k 47k +12V 2n2 BCW31 1n 1n 10n P3 TUNER OSCILLATOR OUTPUT 13k3 P0 SCL SDA ADDRESS REF 10n 18pF 4MHz Optional application utilising on–board crystal controlled oscillator 2 3 4 5 6 7 13 12 11 10 89 116 116 14 15 P2 P1 ADC Fig. 9 Typical appliction APPLICATION NOTES A generic set of application notes AN168 for designing with synthesisers such as the SP5659 has been written. This covers aspects such as loop filter design and decoupling. This application note is also featured in the Media Data Book, or refer to the Mitel Semicondor Internet Site http:// www.gpsemi.com. A generic test/demo board has been pro- duced which can be used for the SP5669. A circuit diagram and list of components for the board is shown in Figs. 10 and 11. The board can be used for the following purposes: (A) Measuring RF sensitivity performance. (B) Indicating port function. (C) Synthesising a voltage controlled oscillator. (D) Testing of external reference SP5669 SP5669 |
