LMX2615W-MPR

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2615W-MPR is an engineering model of the LMX2615-SP, a space-grade wideband phase-locked loop synthesizer. It operates on a single 3.3V supply and covers an output frequency range from 40MHz to 15.2GHz without requiring external doublers or harmonic filters. The device features an integrated voltage-controlled oscillator (VCO) with a figure of merit of -236dBc/Hz and supports JESD204B SYSREF generation. It utilizes a 64-lead CQFP ceramic package and is rated for operation between -55°C and +125°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Space-grade radiation tolerance with single event latch-up immunity exceeding 120MeV-cm2/mg and total ionizing dose resistance up to 100krad(Si).
• Integrated VCO covering a full octave allows direct frequency synthesis down to 40MHz, eliminating the need for half-harmonic filters.
• Supports deterministic phase synchronization across multiple devices and includes programmable delay for SYSREF signals compliant with JESD204B.
• Features ultra-fast VCO calibration suitable for applications requiring abrupt frequency changes or continuous frequency sweeps.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Space communications systems
• Space radar systems
• Phased array antennas and beam forming networks
• High-speed data converter clocking

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the LMX2615W-MPR designation indicates an engineering model intended strictly for evaluation purposes. Confirm that these units are not suitable for production deployment or flight use. Ensure procurement channels provide appropriate documentation regarding the non-production status of this specific ordering suffix before integration into final designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the LMX2615W-MPR variant specifically for engineering evaluation and prototyping phases where flight-qualified hardware is not yet required. This model shares the same functional specifications as the flight model but lacks production qualification. Designers should transition to the 5962R1723601VXC part number for final manufacturing to ensure compliance with space-grade reliability standards.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the LMX2615-SP family of high-performance wideband synthesizers designed for harsh environments. The W-MPR suffix identifies it as an engineering sample within the product line, distinct from mechanical samples and flight models. It provides the same electrical performance characteristics as the qualified versions, facilitating early-stage design validation for aerospace and defense applications.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

For production requirements, substitute with the 5962R1723601VXC flight model. Mechanical samples are available as LMX2615-MKT-MS for physical fit checks only. No other commercial equivalents offer comparable radiation hardness and wideband synthesis capabilities in this package.
