HMC862ALP3ETR

Overview

The HMC862ALP3ETR is a low-noise programmable frequency divider and prescaler manufactured by Analog Devices Inc. It operates within a frequency range of 100 MHz to 24 GHz, supporting divide ratios of 1, 2, 4, and 8. The device requires a supply voltage between 4.75 V and 5.25 V and functions reliably across an operating temperature range of -40 °C to +85 °C. Packaged in a 16-lead LFCSP (3x3 mm) with exposed pad, it integrates high-performance RF division capabilities for wideband applications.

Feature Summary

• Supports multiple divide ratios including 1, 2, 4, and 8 for flexible frequency synthesis
• Operates as both a prescaler and frequency divider up to 24 GHz
• Designed for low noise performance in high-frequency signal processing

Applications

• Wideband frequency synthesizers
• Phase-locked loop (PLL) systems
• High-speed data converter clock generation

Procurement Notes

Verify the specific suffix 'LP3E' against the official Analog Devices datasheet to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the exact electrical characteristics required for your design, as minor suffix variations may indicate different packaging or testing grades. Cross-reference the manufacturer's latest documentation to confirm current availability and lead times through authorized distributors.

Selection Notes

Select this component when a wide operational bandwidth up to 24 GHz is required alongside precise divide ratios. The integrated prescaler functionality simplifies circuit design by reducing the need for external discrete components. Consider the thermal performance of the LFCSP package and ensure adequate PCB layout for heat dissipation given the 5V supply operation.

Part Context

This component belongs to Analog Devices' portfolio of RF and microwave integrated circuits, specifically designed for communication infrastructure and test equipment. It complements other frequency generation and modulation devices in the HMC series, providing essential division stages for complex phase-locked loops and direct digital synthesis architectures.

Replacement Considerations

Consult Analog Devices official substitution guides for compatible frequency dividers. Verify that any alternative part supports the same maximum frequency of 24 GHz and similar divide ratios. Pin compatibility and package dimensions should be confirmed before replacement.
