Programmable Timers and Oscillators

Programmable timers and oscillators are integrated circuits wich contribute to the timing elements of a circuit design. The 8N4DV85AC-0096CDI is a PLL frequency synthesis oscillator specifically designed for wireless applications. This IC enables wireless engineers to precisely control clock frequency and phase to achieve the best performance for their wireless products.

Application Field and Working Principle

The 8N4DV85AC-0096CDI is an integrated circuit with a clock frequency range capability of 6MHz to 200MHz, putting it at the higher end of PLLoscillator frequency range. It is the ideal solution for wireless applications and RFID systems that use frequencies such as 900MHz and 2.4GHz.The 8N4DV85AC-0096CDI circuit consists of two stages. The first stage consists of a phase-locked loop (PLL) oscillator. The oscillator takes input from a reference clock, which is typically an external crystal oscillator and synthesizes it to output an acceptable frequency. The second stage consists of a voltage-controlled oscillator (VCO). The VCO takes the output from the PLL oscillator and adjusts its frequency according to a control voltage. This control voltage may come from the output of an external frequency divider circuit, or from internal circuitry such as a PDL-controlled oscillator, depending on the application.The 8N4DV85AC-0096CDI also has an on-chip programmable digital logic section. The logic can be used to customize the IC’s output to meet specific requirements. This includes frequency multiplication or division, frequencies with duty cycles of up to 80%, and frequency hopping capabilities.
