The ADF4157BCPZ-RL7 is a low-power, wide frequency range, programmable frequency synthesizer. This device makes use of a programmable digital phase-locked loop (PLL) and a dual-modulus fractional-N synthesizer to produce clock signals with a wide frequency range. It features a wide range of output frequencies and a programmable output divider that can be used to achieve high-frequency resolution. Furthermore, the device includes a 12-stage programmable digital filter that can be used to reduce phase noise. This makes the ADF4157BCPZ-RL7 an excellent choice for applications that require low-noise, wide-range frequency synthesizers.
The ADF4157BCPZ-RL7 is suitable for many clock and timing applications, including clock generation, clock synchronization, frequency control, phase-locked loops, and frequency synthesizers. It can also be used for frequency hopping and spread spectrum applications, as well as serial communication systems. The device can be used in a wide range of environments and applications, from cellular base stations to scientific instruments.
The working principle of the ADF4157BCPZ-RL7 is based on a digital phase-locked loop (PLL) and dual-modulus fractional-N synthesizer. The PLL consists of an input divider, phase detector, loop filter, voltage-controlled oscillator, and output dividers. The device can be programmed to produce clock signals with a wide range of frequencies, from 8 MHz to 1500 MHz. The dual-modulus fractional-N synthesizer allows the user to divide the output frequency with a higher resolution. This enables the device to achieve a high-frequency resolution dependent on the reference frequency.
The device is designed for optimizing clock synthesis and minimizing phase noise, jitter, and spurs. It includes a 12-stage programmable digital filter that can be used to reduce phase noise and maintain low-power operation. Additionally, the configurable reference divider and output divider enable fine tuning of the desired frequency, which helps minimize jitter and spurs.
The ADF4157BCPZ-RL7 supports low-power operation, with a power consumption of less than 220 mW at a 20 MHz output frequency. The device can be configured to operate in either normal or standby modes and can be controlled through a 3-wire digital interface. It is available in a thermally enhanced, space-saving TSSOP package, making it suitable for compact applications.
In summary, the ADF4157BCPZ-RL7 is a low-power, wide frequency range, programmable frequency synthesizer. It is well-suited for numerous clock and timing applications, including clock generation, clock synchronization, frequency control, phase-locked loops, and frequency synthesizers. The device supports low-power operation, a 12-stage programmable digital filter for minimizing phase noise, and a wide range of output frequencies. It is available in a space-saving TSSOP package, making it suitable for a variety of applications.
