LMX2331LTMX/NOPB

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2331LTMX/NOPB is a PLLatinum frequency synthesizer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports input signals in CMOS or TTL logic levels, producing CMOS outputs. The device features a maximum output frequency capability of 2 GHz for the main path and 600 MHz for an auxiliary path, with a fixed input-to-output ratio of 3:1. It is designed for surface-mount installation in a 20-TSSOP package (0.173 inch width). The component functions as a single-channel clock generator suitable for timing applications across an operating temperature range of -40°C to +85°C.
