Генерация и распределение тактового сигнала

Компания Analog Devices предлагает продукты для формирования и распределения тактовых сигналов, предназначенные для применения в инфраструктуре беспроводных сетей, измерительном оборудовании, широкополосной связи, автоматизированном испытательном оборудовании и других областях, где требуется очень малое дрожание фазы сигнала – на уровне менее пикосекунд. Эти компоненты идеально подходят для синхронизации быстродействующих аналого-цифровых и цифро-аналоговых преобразователей (АЦП и ЦАП). Выпускаемые компанией Analog Devices ИМС формирования и распределения тактовых сигналов включают в себя схемы ФАПЧ, делители частоты, функции регулировки фазового сдвига, а также выходные драйверы, которые интегрированы в одном миниатюрном корпусе.
