LMX1602SLBX

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX1602SLBX is a monolithic dual frequency synthesizer from the PLLatinum family, designed for local oscillator subsystems in radio transceivers. It operates with a Main PLL frequency range of 100 MHz to 1.1 GHz and an Aux PLL range of 40 MHz to 500 MHz. The device utilizes a 1.1 GHz/1.1 GHz dual modulus prescaler configuration (16/17) for both loops. It features low current consumption of 5.0 mA at 3V and includes digital filtered lock detects. Power supply voltage ranges from 2.7V to 3.6V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Dual independent phase-locked loops with selectable gain charge pumps
• Microwire serial interface for programmable counter configuration
• Digital filtered lock detect functionality for both Main and Aux PLLs
• Hardware-controlled powerdown mode for individual loop management

Clock Generators, PLLs, Frequency Synthesizers Applications

• Cordless phones

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 16-pin TSSOP specification. Review datasheet revision history for any parameter updates. Ensure handling procedures account for ESD sensitivity during assembly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a dual-loop synthesizer with a 1.1 GHz main output and 500 MHz auxiliary output is required. Verify that the application supports the 16/17 prescaler ratio for both loops. Ensure the external VCOs match the specified input frequency ranges and control voltage requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The LMX1602 belongs to the Texas Instruments PLLatinum family alongside the LMX1600 and LMX1601. These devices share a common architecture but differ in maximum operating frequencies and prescaler configurations. The LMX1602 specifically targets applications requiring a 1.1 GHz main path and a lower frequency auxiliary path.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

LMX1600SLBX/NOPB and LMX1601SLBX/NOPB are part of the same family but offer different frequency options. Direct substitution requires verifying that the specific prescaler ratios and frequency ranges of the alternative part meet the design requirements.
