Programmable timers and oscillators are digital electronic devices that control the timing of events in computing and electronic systems, such as generators and machinery. The LMK61A2-100M00SIAT is a type of these devices that are particularly suited for high-accuracy timing applications.

LMK61A2-100M00SIAT is the latest generation of low jitter programmable oscillators from Texas Instruments. This highly precise timing device is designed to operate with little jitter and excellent performance across a wide temperature range of -10°C to 85°C. This makes it suitable for a range of applications including military, aerospace, industrial and test & measurement systems.

The LMK61A2-100M00SIAT features two separate oscillators which each have inputs that can be programmed individually. This allows the device to be used in a wide range of applications including clock distribution, clock synchronization, or generating complex waveforms. The output frequency can be programmed up to 200 MHz and is typically less than 5 parts-per-million (PPM) accurate from -40°C to 85°C over an extended temperature range.

The LMK61A2-100M00SIAT also features programmable power-down/low-power modes which reduce the current consumption of the device to as low as 5 mA, making it suitable for low power applications. This device also offers very low jitter performance, which is critical for high speed and precision applications.

Aside from its low jitter performance, the LMK61A2-100M00SIAT also features a range of enhanced features and functions, such as duty cycle and open-drain options. This makes the device well suited to a variety of application fields, including networking, communications, computing and wireless systems.

In terms of the working principle of this device, the LMK61A2-100M00SIAT is essentially a digital timer that uses an internal crystal oscillator to generate an exact output frequency based on an input reference frequency. The frequency of the output is controlled by a programmable divider that is set via programming port pins.

This device also features a slew rate limiter circuit that can be used to reduce the rate at which the frequency of the output is changed. This helps ensure that the output frequency is tightly matched to the programmed frequency and limits any overshoot or undershoot of the output frequency.

In summary, the LMK61A2-100M00SIAT is an ideally suited to high accuracy timing applications. It boasts a low jitter performance, programmable divider, power-down/low-power modes and slew rate limiter, making it suitable for a wide range of applications and uses.
