DS1090U-16

Clock Generators, PLLs, Frequency Synthesizers Overview

The DS1090U-16 is a low-frequency, spread-spectrum silicon oscillator manufactured by Analog Devices Inc. (Maxim Integrated). It operates at a fixed output frequency of 16 MHz and is housed in an 8-pin uSOP package with dimensions of 3.1 x 3.1 x 0.95 mm. The device functions as a dithered oscillator designed to reduce peak radiated emissions from switched-mode power supplies and other low-frequency applications. It utilizes a resistor-programmed master oscillator and factory-programmed clock prescaler architecture.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The DS1090U-16 belongs to the DS1090 series of EconOscillator devices. This family provides low-cost, programmable oscillators where the output frequency is determined by an external resistor and internal prescalers. The 'U' suffix indicates the uSOP package type, while '-16' specifies the 16 MHz frequency variant within the 125 kHz to 8 MHz general range of the series, though this specific part is fixed at 16 MHz.
