Application Field

The SI50122-A4-GM is a programmable oscillator designed primarily for industrial applications. It is designed to be used in applications where precision control and stability of the clock frequency are required, such as in medical equipment, industrial automation, instrumentation, and communications systems. As the clock frequency is programmable, it is also suitable for complex real-time embedded systems.

The SI50122-A4-GM is capable of producing a range of frequencies from 1kHz to 1.3GHz. It can also be used as a reference clock in systems which require precision synchronization, such as when working with multiple frequencies over short distances. The device features a built-in voltage-controlled oscillator, as well as the ability to program and set the output frequency.

Working Principle

The SI50122-A4-GM is an integrated oscillator consisting of a voltage-controlled oscillator with an amplifier, a divider, an analog-to-digital converter, and an internal clock generator. The clock generator produces a low-frequency clock signal which is then distributed to the voltage-controlled oscillator, the amplifier, and the divider. The voltage-controlled oscillator converts the input signal into a sinusoidal output. This output is then amplified and used to drive the divider. The divider divides the oscillator output by a set number (N) and produces a signal whose frequency is equal to the CLKOUT frequency divided by N. The analog-to-digital converter converts the output of the divider into a digital signal which is then sent out as the clock signal.

The SI50122-A4-GM can be programmed to produce various output frequencies within the range of 1kHz to 1.3GHz. The frequency can be programmed via the digital interface, which is usually connected to a microcontroller. The device can also be used as a reference clock, which can be synchronized with external signals. The SI50122-A4-GM has an operating temperature range of -40°C to +85°C.

In summary, the SI50122-A4-GM is a low-frequency clock signal generator designed for industrial applications. It has an operating temperature range of -40°C to +85°C and is capable of producing frequencies from 1kHz to 1.3GHz. The frequency can be programmed using the digital interface and it can be used as a reference clock for synchronizing with external signals. The SI50122-A4-GM is a versatile and reliable device for generating low-frequency clock signals in a wide variety of industrial and embedded systems.
