Programmable oscillators are among the most important components in the communication and signal processing industry. They are used to control the frequency and timing of signal pulses in order to transmit data or provide timing control. The SIT9005ACB2G-25ND programmable oscillator is a high precision, low profile, and low power device suitable for many applications. This article will focus on the application field and working principle of this oscillator.

The SIT9005ACB2G-25ND oscillator is a 5.0 x 3.2 mm low profile ceramic package with a fundamental frequency range of 25.00MHz to 50.00 MHz. It features a low jitter of 2.66ps, low power consumption of only 8.5mA, and a wide temperature range of -40°C to 85°C. It has a fast lock time of 5.0ns and fast frequency switching time of 4.0ns, making it ideal for high speed data transmission and signal processing.

In terms of application field, the SIT9005ACB2G-25ND oscillator is suitable for a wide range of applications, including communication, networking, test and measurement, industrial, automotive, personal computers, and many other applications. It can be used in wireless communication systems for frequency synthesis, base stations for GPS and GSM networks, broadcast audio and video receivers, HD digital video transcoding, motor control systems, medical, and automotive applications.

The SIT9005ACB2G-25ND programmable oscillator features a unique “write only” MEMs technology that is easy to program and reconfigure. This technology requires only a two-word instruction set, minimizing the programming time and allowing for higher data rates. The MEMs are composed of a 2.0 x 2.0 mm thick resistive device, which consists of two layers of a permalloy and a gold layer on the walls and ceiling of the MEMs’ inner cavity. This layer creates a barrier between the space charge and the permalloy. When a voltage is applied, the permalloy is magnetically polarized and creates a field that generates an ac voltage across the MEMs’ structure.

This ac voltage is used to supply the acceleration needed to move the MEMs actuator. The actuator is normally in the rest position, and when it’s energized, it moves in the direction of the applied magnetic field and changes the inductance of the MEMs’ cavity. This change in inductance is sensed by the oscillator’s circuit, which produces an output frequency that is proportional to the electric field strength. The MEMs technology allows for easy configuration and fast frequency switching.

In summary, the SIT9005ACB2G-25ND is a versatile programmable oscillator suitable for many applications, such as communication, networking, test and measurement, and industrial. It features a write only MEMs technology and has a fast lock time and switching time, making it perfect for high speed applications. It also consumes very little power, has a wide temperature range, and is extremely compact.
