**LTC6900IS5#TRMPBF: A Low-Power SOT-23 Oscillator for Precision Frequency Generation**
In the realm of modern electronic design, the demand for compact, efficient, and precise clock sources is ubiquitous. The **LTC6900IS5#TRMPBF** from Analog Devices stands out as a premier solution, **integrating a complete precision oscillator into a tiny SOT-23 package**. This device is engineered to generate a square wave output frequency programmable from 1kHz to 20MHz, catering to a wide array of applications from data conversion to frequency synthesis.
The core of the LTC6900's appeal lies in its **revolutionary resistor-set frequency programming methodology**. Unlike crystal oscillators or complex phase-locked loops (PLLs), this oscillator requires only a single external resistor to set its output frequency with exceptional accuracy. This simplicity drastically reduces the bill of materials (BOM), saves valuable board space, and accelerates the design process. The relationship between the resistance (RSET) and frequency (fOSC) is linear and predictable, governed by the formula fOSC = 20MHz * (10kΩ / RSET), ensuring straightforward design calculations.
A key advantage of the LTC6900 is its **remarkably low power consumption**, a critical feature for battery-powered and portable devices. The chip operates over a wide supply voltage range of 2.7V to 5.5V, drawing a mere 475µA at 3V with a 20MHz output. Its power-down feature reduces current consumption to less than 5µA, making it an ideal choice for power-sensitive applications where extending battery life is paramount.
Furthermore, the device **excels in providing excellent frequency stability** over variations in supply voltage and temperature. It exhibits very low jitter, typically 0.5% peak-to-peak, which is crucial for maintaining signal integrity in high-performance systems like communication interfaces and precision measurement equipment. The combination of a small footprint, low power, and high accuracy makes it a superior alternative to traditional clock generation circuits that often require multiple discrete components.
The LTC6900IS5#TRMPBF is particularly well-suited for use as a master clock for microcontrollers, data converters (ADCs/DACs), and as a baud rate generator for serial communications. Its robust design and ease of use empower engineers to implement reliable clocking solutions quickly and effectively.
