Programmable oscillators are oscillators with programmable output frequency and amplitude characteristics. SG-8003CE-PCM is one of the most popular programmable oscillators in the market. It is widely used in applications such as telecommunications, medical, industrial, and aerospace. This article will discuss the application field and working principle of SG-8003CE-PCM.

SG-8003CE-PCM supports three output formats: TTL, differential PECL (positive emitter coupled logic) and differential ECL (emitter coupled logic). The TTL output has noise within 0.45 NSRMS, while the ECL output has 0.2 NSRMS noise. It can provide an output frequency of up to 0.9 GHz and has low power consumption of 45mA. The temperature range of the SG-8003CE-PCM is from -55°C to +150°C, making it suitable for a wide range of applications including space environments. It also has a wide selection of parameters for frequency, amplitude and duty cycle, allowing for great flexibility in its use.

The SG-8003CE-PCM utilizes a programmable frequency synthesizer to control the frequency and amplitude. The synthesizer consists of three stages: a phase detector, a charge pump, and a loop filter. The phase detector generates a signal proportional to the difference in phase between the input and output. This signal is then sent to the charge pump, which in turn generates a current proportional to the phase difference. The loop filter receives this current, smooths it out and provides a voltage output for the frequency synthesizer. This voltage is then used to control the frequency and amplitude of the output.

In addition, SG-8003CE-PCM also has programmable digital functions such as gain control, linearity control and distortion control. These functions allow users to control the output frequency and amplitude accurately according to their requirements. The device also offers other features such as fast lock and stable frequency output making it a very reliable and accurate programmable oscillator.

SG-8003CE-PCM has wide applications in fields such as telecommunications, medical, industrial and aerospace. It is especially suitable for communication applications that require accurate frequency control (e.g. CDMA, UMTS, WCDMA and GSM). Its ability to control the frequency and amplitude accurately makes it a great choice for military, industrial and medical applications. Additionally, its wide temperature range makes it suitable for aerospace applications such as satellite communications and air traffic control systems.

In conclusion, SG-8003CE-PCM is one of the most popular programmable oscillators in the market. It has wide applications and is suitable for a variety of tasks from telecommunications to aerospace. It is also an accurate and reliable programmable oscillator with excellent performance. SG-8003CE-PCM is a great choice for any project that requires precise frequency and amplitude control.
