The ADF4108BCPZ-RL7 is a monolithic, dual-modulus prescaler suitable for use in frequency synthesizers, clock generators, and clock dividers and multipliers in digital PLL frequency synthesizers. It operates from 0.8 V to 3.6 V and is specified from -40 °C to +125 °C. The ADF4108BCPZ-RL7 has two nonoverlap outputs for stable divide-by-N and divide-by-2N operation, with a wide switching frequency range of 250 kHz to 2.1 GHz. The part also includes a low-noise, high-accuracy, voltage-controlled oscillator (VCO) frequency divider.

The ADF4108BCPZ-RL7 is designed to be used in frequency synthesizer and clock generator applications, where the frequency of the output clock or oscillator must be accurate, fast-switching, and low-noise. The device can generate clock outputs at any frequency up to 2.1 GHz and can be used in any system clock generator circuit. In addition, the part can be used in PLL frequency synthesizers to generate a stable output clock with high accuracy and low jitter.

The ADF4108BCPZ-RL7 includes a voltage-controlled oscillator (VCO) frequency divider to provide circuit flexibility and eliminate the need for external frequency dividers. This feature allows users to select the exact desired output frequency with great accuracy, eliminating errors caused by mismatches in divider ratios. The VCO frequency divider also provides jitter performance benefits by allowing the output frequency to be adjusted with high accuracy and low jitter.

The ADF4108BCPZ-RL7 uses a charge pump to generate the required voltages, thus eliminating the need for external voltage regulation and providing the user with greater flexibility when integrating the device into a system. The device also includes a 2-wire serial interface, allowing the user to program the required dividing ratios, bypass dividers, and operate in power-down mode.

The ADF4108BCPZ-RL7 is a versatile device that is suitable for a wide range of frequency synthesizer, clock generator, and PLL frequency synthesizer applications. Its excellent jitter and frequency accuracy, wide operating range, and low power consumption makes it an ideal choice for any system clock generator circuit or PLL frequency synthesizer.
