Analog Devices Inc. HMC828LP6CE Fractional-N PLL with Integrated VCO

The HMC828LP6CE from Analog Devices Inc. is a highly integrated, high-performance Fractional-N Phase-Locked Loop (PLL) with an integrated Voltage-Controlled Oscillator (VCO) that offers advanced frequency synthesis for a wide range of RF applications. This device is part of the Hittite Microwave Corporation product line, which is known for its high-quality microwave and RF solutions.

The HMC828LP6CE incorporates a wideband, low phase noise VCO, which can generate frequencies from 2.6 GHz to 3.9 GHz, making it an ideal choice for applications such as wireless infrastructure, test and measurement equipment, and satellite communication systems. It features a fractional frequency division capability, which allows for fine frequency resolution and a reduced need for external components.

This PLL with an integrated VCO comes in a compact 6x6 mm QFN (Quad Flat No-Lead) package, which saves board space and simplifies the design process. The device also includes an integrated phase detector and a delta-sigma modulator, which work together to provide low noise and spurious performance while maintaining high-frequency stability.

Key features of the HMC828LP6CE include:

• Wide frequency range: 2.6 GHz to 3.9 GHz
• Low phase noise performance
• Fractional-N frequency synthesis
• Integrated VCO with no need for external loop filter components
• Programmable charge pump current
