HMC837LP6CETR

PLL Single 1025 to 4600MHz 40Pin QFN T/R

Product Details

The HMC837LP6CE is a fully functioned Fractional-N Phase-Locked-Loop PLL Frequency Synthesizer with an Integrated Voltage Controlled Oscillator VCO. The synthesizer consists of an integrated low noise VCO with a triband output, an autocalibration subsystem for low voltage VCO tuning, a very low noise digital Phase Detector PD, a precision controlled charge pump, a low noise reference path divider and a fractional divider.

The fractional synthesizer features an advanced delta-sigma modulator design that allows both ultra-fine step sizes and low spurious products. The phase detector PD features cycle slip prevention CSP technology to allow faster frequency hopping times. Ultra low in-close phase noise and low spurious also allows wider loop bandwidths for faster frequency hopping and low micro-phonics.

For theory of operation and register map refer to the "PLLs with Integrated VCO - RF VCOs" Operating Guide.
