The LMX2372SLBX is a dual frequency synthesizer designed for RF personal communications applications, capable of operating at frequencies up to 1.2 GHz. It utilizes a digital phase-locked loop (PLL) technique to generate stable, low-noise control signals for voltage-controlled oscillators (VCOs). The device features a selectable prescaler, allowing for 16/17 or 8/9 division ratios, which accommodate input frequencies below 1.2 GHz and 550 MHz, respectively. This synthesizer operates with a supply voltage range of 2.7V to 5.5V and exhibits low current consumption, typically drawing 4.0 mA at 3V. The LMX2372SLBX supports a low-voltage MICROWIRE interface for serial data transfer, making it compatible with low-voltage baseband processors. It is available in a compact 24-pad chip scale package, suitable for space-constrained designs. The device is ideal for applications in portable wireless communications, dual-mode cellular systems, and spread spectrum communication systems.
