DS1099U-TJ+

Clock Generators, PLLs, Frequency Synthesizers Overview

The DS1099U-TJ+ is a low-frequency dual EconOscillator manufactured by Analog Devices Inc./Maxim Integrated. It generates two independent square-wave outputs with frequencies programmable from 0.25Hz to 1.048MHz. The device operates on a single supply voltage ranging from 2.7V to 5.5V and requires no external timing components. Each output can sink up to 16mA, enabling direct LED driving. It features independent output enables and CMOS/TTL-compatible logic levels.
