The LTC6930HDCB-5.00 is an innovative device that utilizes the newest advances of oscillator and timer technology for precisely timing long and short intervals with programmable precision, designed specifically for clock/timing applications. It is built with a simple yet powerful circuit to ensure optimum performance in all conditions, and its superior, built-in accuracy and stability are key factors for the user, who can select the best of both oscillator and timer capabilities for their particular application.

The LTC6930HDCB-5.00 is a fully integrated, dual-function timer and oscillator, featuring an impressive range of configurable features and frequency characteristics. The device combines an oscillator based on a quartz crystal and an integrated, adjustable timer that is programmed and configured through an easy-to-use serial interface. Its low-jitter output makes the device a perfect choice for timing applications, while alternative operating modes allow it to be used as a programmable oscillator in radio frequency and wireless applications.

The fundamental principle of the LTC6930HDCB-5.00 is that it uses multiple timing elements to generate a precise, periodic output signal. It begins with a low-jitter, quartz crystal (TQ) oscillator as the main timing element, which provides the most accurate, stable, and reliable timing base. This is combined with an adjustable programmable counter (PC) and one or two independent oscillators (RO and R1 or R2) to deliver precise, low-jitter frequencies that are not achievable with a single crystal oscillator.

The oscillator is the main element of the LTC6930HDCB-5.00. It is composed of a quartz crystal, passive components, and an integrated timer. The crystal provides the source frequency to the internal oscillator, also known as a precision clock source. This internal clock is then compared to a reference (REF) to create a pulse width modulation (PWM) signal, which is used to output a precise periodic signal. The output can be programmed with a programmable counter, which allows the frequency, duty cycle, and pulse width to be reconfigured as needed.

The timer section has several additional features including programmable delays, pulse width selection, and programmable skew. The delay feature allows for the start of the periodic signal to be adjusted, providing flexibility to the timing of the output signal, as well as several possibilities for pulse width control - from a single pulse to many pulses across several or many cycles.

The built-in programmable counter is used for both frequency and phase adjustment of the periodic signal, changing the length of the pulse output in order to make the signal more stable. This counter also has the capability to program any type of duration and can be used to set two or more intervals with different phase shifts. Additionally, the counter can also be configured with a skew as needed, providing further customization of the signal\'s timing properties.

The robust timing capabilities of the LTC6930HDCB-5.00 can be applied in many different applications, some of which include communications, instrumentation, test and measurement, media and television broadcast, automotive, industrial, and more. Its superior performance in terms of accuracy, stability, and flexibility make it a reliable and highly dependable choice for occasional and critical clock/timing applications.
