Description
AI
The HMC783LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled Oscillator (VCO). The input reference frequency range is 100 kHz to 220 MHz while the advanced delta-sigma modulator design in the fractional PLL allows both ultra-fine step sizes and very low spurious products. The highly integrated structure provides excellent phase noise performance over temperature, shock and process. The HMC783LP6CE is packaged in a leadless QFN 6 x 6 mm surface mount package. The output power is 11 dBm typical, making the HMC783LP6CE ideal for driving the LO port of many of Hittite’s Hi Linearity and I/Q mixer products.For theory of operation and register map refer to the "PLLs w/ Integrated VCO - Microwave VCOs" Operating Guide.ApplicationsVSAT RadioPoint-to-Point / Multi-Point RadioTest Equipment & Industrial ControlMilitary End-UsePhased Array Applications
