LMX2572LPRHAR

The LMX2572LP from Texas Instruments is a high-performance, low-power wideband RF synthesizer capable of generating frequencies from 12.5 MHz to 2 GHz without an internal doubler. It offers excellent PLL performance while consuming only 70 mA at a 3.3-V supply.

Key electrical specifications include a phase noise of -124 dBc/Hz at a 100-kHz offset with an 800-MHz carrier, a PLL figure of merit of -232 dBc/Hz, and a PLL normalized 1/f noise of -123.5 dBc/Hz. It features a 32-bit fractional-N divider, programmable input multiplier, and supports ramp and chirp functions. The device also supports FSK direct digital modulation, discrete level FSK, and pulse-shaping FSK.

Designed for applications like digital mobile radio (DMR) and wireless microphones, the LMX2572LP allows for synchronization of output phase across multiple devices and enables applications requiring deterministic delay between input and output. It offers two programmable output power levels and differential outputs.

This synthesizer is available in a 40-VQFN (6x6) surface mount package. It operates within a temperature range of -40°C to 85°C (TA) and requires a single 3-V to 3.5-V power supply.
