The ADF4355-3BCPZ is a wideband, frequency synthesizer phased-locked loop (PLL) device developed by Analog Devices. ADF4355-3BCPZ frequency synthesizer uses a dual-modulus prescaler, a fastlock range select architecture, and a newly designed digital PLL core. It is designed to choose the optimal loop parameters to achieve low jitter and fast switching. Additionally, due to its wide frequency coverage (3.3–3.9 GHz) and robust design, the ADF4355-3BCPZ can be used in multiple applications, such as communication systems, radio receivers, and commercial test and measurement systems.

The ADF4355-3BCPZ incorporates both a pulse width modulation (PWM) and direct digital synthesizer (DDS) outputs. It has an output frequency range of 500 kHz to 3.9 GHz and a resolution of almost 1 Hz for good frequency precision. The ADF4355-3BCPZ boasts very good frequency control, with a frequency switching time of less than 1 μs, and typical RMS phase jitter performance of 17fs, making it an ideal choice for many applications. It also features an integrated GFET prescaler, enabling direct injection of a +3.3V to +3.9V reference clock, resulting in improved resistor-capacitor (RC) oscillator stability and improved power supply rejection. This helps to ensure that the device operates reliably in a variety of environments.

The ADF4355-3BCPZ can be used in many applications, such as wireless communication systems, base station receivers, public safety radios, and instrumentation. In radio broadcasting applications it can be used to lock the radio signal up to 3 GHz. The device can also be useful in public safety radio applications, as it can be used to synthesize frequencies up to 3.9 GHz. Additionally, it can be used to generate tests signals for instrumentation, such as oscilloscopes, spectrum analyzers, and signal generators. The ADF4355-3BCPZ can even be used for frequency synthesis for radar systems, as it has a fast frequency switching times and good frequency control, which is essential for good radar performance.

The ADF4355-3BCPZ has an integrated digitally controlled oscillator (DCO) that allows for direct control of the output frequency. The device works in two modes, using a loop bandwidth and a fastlock range select. The loop bandwidth mode is divided into three categories, fast (1.25 MHz nominal), normal (12.5 kHz nominal), and slow (0.15 kHz nominal). These two parameters are chosen depending on the application. The fastlock range select parameters are preset at the factory and are not adjustable by the user.

The ADF4355-3BCPZ has very low power consumption and is designed to operate over a temperature range of -40°C to 85°C. This makes it suitable for use in applications that must operate in any environment. The device is compatible with a wide range of devices, such as microcontrollers and FPGAs. It also has a built-in programmable phase noise, which can be used to reduce phase noise and improve system performance. Additionally, the device has a programmable output power level, in order to reduce fading of the signal, which is especially important in satellite applications.

The ADF4355-3BCPZ is an analog frequency synthesizer that is suitable for a variety of clock/timing applications requiring fast frequency switching and low phase noise. The device is designed to provide low power consumption and wide frequency range. Additionally, the device has built-in phase noise control which can help reduce phase noise and improve system performance. The ADF4355-3BCPZ is an ideal choice for a variety of applications, such as radio broadcasting, public safety radios, radar systems, instrumentation and more.
