Подробнее о продукте

Синтезатор частот ADF4107 может быть использован для реализации гетеродинов в каскадах повышения и понижения частоты беспроводных приемников и передатчиков. Он включает в себя малошумящий цифровой фазочастотный детектор (PFD, Phase Frequency Detector), прецизионную схему накачки заряда, программируемый делитель опорной частоты, программируемые счетчики A и B, а также предварительный делитель с переключаемым модулем (P/P+1). Счетчики A (6-битный) и B (13-битный) совместно с предварительным делителем с переключаемым модулем (P/P+1) образуют делитель обратной связи N (N = BP+A). Кроме того, 14-битный счетчик опорной частоты (счетчик R) позволяет управлять частотой сигнала REFIN на входе фазочастотного детектора. Для реализации полнофункционального синтезатора с фазовой автоподстройкой частоты (ФАПЧ) на основе данного компонента необходимо использовать внешние петлевой фильтр и генератор, управляемый напряжением (ГУН). Очень широкая рабочая полоса частот компонента дает возможность избежать применения удвоителей частоты во многих высокочастотных системах, благодаря чему упрощается архитектура системы и снижается ее стоимость.

Product Details

This page contains ordering information for the evaluation board used to evaluate the ADF4107 PLL Frequency Synthesizer.

This evaluation board requires an SDP Controller board for connection to the PC. The SDP controller board connects to the PC via USB 2.0. The evaluation board will connect to the SDP controller board. The evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate through the SDP Controller board, to the evaluation board. The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CS1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
