Overview
The HMC764LP6CETR from Analog Devices Inc. is a fully functional Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO). This component is designed to operate within the RF frequency range of 7.3 GHz to 8.2 GHz, making it suitable for various high-frequency applications. The HMC764LP6CETR features advanced delta-sigma modulator design, allowing for ultra-fine step sizes and very low spurious products. It is packaged in a 40-lead QFN (Quad Flat No-Lead) 6 x 6 mm surface mount package, which is RoHS-compliant and has a low stress injection molded plastic body.
