The 843001AG-21LF-HT (hereafter referred to as the 843001) is a digital frequency synthesizer & devices that provide an adjustable frequency output. It is a comprehensive digital system and includes advanced features such as several types of programmable reference clocks, wide range of digital VCOs and oscillators, adjustable pre- and post divider circuits, and powerful interleaving synthesis. This type of synthesizer is mainly used for integrated clock and oscillator designs, such as in communications and timing applications. The 843001 is designed for low-power and high-performance, and is available in a range of package options.

The 843001 is a dual-channel frequency synthesizer, designed to provide an adjustable frequency output from a selectable input reference clock at 8 kHz to 1.2 GHz. The clock is controlled by a programmable reference clock, which can be configured to operate at 8 kHz, 10 kHz, 11 kHz, 15 kHz, 20 kHz, 25 kHz, 50 kHz, 100 kHz and 200 kHz. The adjustable pre- and post-divider circuits allow for further signal flexibility by allowing fractional frequencies up to 1.2GHz.

The 843001 features a maximum reference clock frequency of 8.0GHz and can operate in a variety of working modes, including two-phase synchronization, dynamic bypass, clock/oscillator synthesis, and bus-controlled operation. The two-phase synchronization mode offers dynamic control of the device with an adjustable clock source. This mode allows the user to select a clock rate, and the 843001 then calculates and adjusts the required output frequency accordingly.

The dynamic bypass mode offers a high-speed data interchange between the input clock and the output frequency. This helps to reduce power consumption and time waiting for the clock output to switch frequencies. The clock/oscillator synthesis mode accommodates wide frequency ranges, allowing for frequencies up to 1.2GHz. It is particularly useful in radios and communication systems.

Finally, the bus-controlled operation of the 843001 enables various outputs to be realized on demand. This is especially useful in radio and digital applications, by enabling an adjustable frequency output without the need for frequent manual adjustments. This mode also allows for flexible programming of the device, due to its compatibility with several types of industry standard bus systems.

The 843001 has a wide range of features, making it perfect for use in many clock and timing applications. Its two-phase synchronization mode is especially suitable for automated systems, while its dynamic bypass mode helps to reduce power consumption. Its capability to synthesize frequent output frequencies, its compatibility with a variety of bus systems and its adjustable output frequency make it ideal for applications in radio and communication systems. Overall, the 843001 is designed for low-power and high-performance, making it an ideal choice for those looking for a digital frequency synthesizer & devices for their next clock and timing project.
