The TB-29.4912MDD-T is a surface-mount device based on a MEMS (micro-electromechanical systems) timing element and a temperature sensor. It is a feedback-controlled oscillator, meaning that it relies on a closed loop to maintain a stable frequency output. The MEMS timing element consists of a sliced single-crystal quartz resonator, while the temperature sensor is a thermistor or thermoelectric device. The frequency output of the oscillator is determined by the resonator, while the temperature sensor is used to provide a temperature compensation signal to the circuit. When the operating temperature of the oscillator changes, the temperature sensor will sense the change and send a correction signal to the oscillator circuit, which will adjust the frequency of the output to maintain a stable frequency.

The TB-29.4912MDD-T utilizes a wide range of technologies to provide superior accuracy and reliability. Its frequency stability is guaranteed over a wide temperature range, with a tight frequency tolerance of ±2 ppm (±0.02Hz), and a wide operating temperature range of -40°C to +85°C. It also has an integrated temperature sensor that is self-calibrating for better long-term stability and reliability. The device is designed to ensure low power consumption, with an operating current of only 2.15 mA for 2.5 V and 3.17 mA for 3.3 V.

The TB-29.4912MDD-T is a high performance oscillator that offers reliable frequency stability and low power consumption at a competitive price. It is ideal for applications that require low frequency jitter, such as RF/wireless systems, medical devices, consumer electronics and automotive systems. With its integrated temperature sensor, the TB-29.4912MDD-T oscillator provides superior accuracy and reliability over a wide operating temperature range.
