ADF4159WCCPZ

Overview

The ADF4159WCCPZ is an automotive-qualified, 13 GHz fractional-N frequency synthesizer manufactured by Analog Devices. It features a low-noise digital phase frequency detector (PFD) with frequencies up to 110 MHz and a precision charge pump. The device utilizes a 25-bit fixed modulus for sub-Hertz frequency resolution and supports direct modulation via FSK and PSK functions. It includes internal circuitry for fast and slow waveform generation, such as sawtooth and triangular ramps. Power supplies operate at 2.7 V to 3.45 V for analog sections and 1.62 V to 1.98 V for digital logic.

Feature Summary

• RF bandwidth extending to 13 GHz with PFD frequencies up to 110 MHz
• 25-bit fixed modulus enabling sub-Hertz frequency resolution
• Automotive qualification compliant with AEC-Q100 standards
• Integrated high-speed and low-speed FMCW ramp generation capabilities

Applications

• FMCW radar systems
• Communications test equipment
• Communications infrastructure

Procurement Notes

Verify the specific W suffix indicates automotive grade qualification when sourcing. Confirm package availability in LFCSP-24 format. Ensure supply chain documentation matches the Rev E datasheet specifications for the ADF4159 family.

Selection Notes

Select this component for applications requiring high-frequency synthesis with strict automotive reliability standards. The 110 MHz PFD frequency allows for wide loop bandwidths, facilitating rapid lock times without modifying external loop filters. Ensure power supply rails match the specified 2.7–3.45 V and 1.62–1.98 V ranges.

Part Context

The ADF4159WCCPZ belongs to the ADF4159 series of direct modulation and fast waveform generating fractional-N PLLs. The 'W' designation specifically denotes automotive-grade qualification, distinguishing it from standard industrial variants while maintaining identical electrical performance characteristics.

Replacement Considerations

Standard industrial versions like the ADF4159CCPZ share identical electrical specifications but lack automotive certification. Verify if the application strictly requires AEC-Q100 compliance before substituting non-W suffix parts.
