Overview

LMX2582RHAR: High Performance, Wideband PLLatinum™ RF Synthesizer With Integrated VCO

General Description

The LMX2582RHAR is a high-performance, wideband RF synthesizer with an integrated VCO, designed for applications requiring low phase noise and high frequency accuracy. It supports a frequency range from 20 MHz to 5.5 GHz and features both fractional-N and integer-N modes. The device integrates a low-noise VCO and a high-performance PLL, making it suitable for demanding applications such as test and measurement equipment, cellular base stations, and high-speed data converters.

Features

Output Frequency Range: 20 MHz to 5.5 GHz
VCO Frequency Range: 3.55 GHz to 7.1 GHz
Input Clock Frequency: Up to 1.4 GHz
Phase Detector Frequency: Up to 200 MHz (up to 400 MHz in integer-N mode)
Low Phase Noise: VCO phase noise of –144.5 dBc/Hz at 1-MHz offset for 1.8-GHz output
Low Jitter: 47 fs RMS jitter (12 kHz to 20 MHz) for 1.8 GHz output
Flexible Input Signal Path: Programmable OSCin doubler, pre-R divider, multiplier, and post-R divider
Programmable Output Power: High output power with programmable pull-up components
SPI or uWire Interface: Compatible with 1.8-V and 3.3-V logic levels
Single Power Supply: 3.3 V operation
