Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and moisture sensitivity level (MSL 1) handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints for the 16-TFQFN CSP form factor before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-channel PLL frequency synthesizer with CMOS I/O is required. Consider the 2.8GHz maximum clock frequency limit and the specific 2:1 input-to-output ratio constraints. Evaluate thermal performance within the -40°C to +85°C operating range for the intended application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the PLLatinum™ family of clock generators and PLL frequency synthesizers. It shares the 16-TFQFN CSP packaging style with related models such as the LMX2326SLBX/NOPB and LMX1600SLBX/NOPB, though specific electrical parameters and internal prescaler configurations may vary across the series.
