Oscillators are circuits that produce a periodic signal, usually a sinusoidal waveform, that can serve many applications. One of oscillators is SG-8002CE 25.0000M-PCMB, and this article will discuss its application field and working principle.

SG-8002CE 25.0000M-PCMB is suitable for a wide range of applications including clocks, communications, automotive, network components, transport control and sensing equipment. It is designed to deliver low jitter performance and low power consumption. Features of the SG-8002CE 25.0000M-PCMB oscillator include a 25 MHz frequency, +/- 20 ppm frequency stability, an operating voltage of 3.3 V, common-mode noise of -80 dBc to -120 dBc, a low power consumption of 100 mW, and a power-down isolation of greater than 20 dB. The package size of SG-8002CE 25.0000M-PCMB is 6.00mm x 4.50mm.

The working principle of SG-8002CE 25.0000M-PCMB is based on a voltage-controlled oscillator (VCO) circuit. It consists of a low power CMOS VCO which drives an amplifier. The oscillator frequency is determined by the impedance of the tuning capacitor and a resistor in series as the feedback circuit of the VCO. A voltage-controlled current source (VCCS) is connected to the tuning capacitor, which determines the oscillator frequency. The output from the amplifier is then taken from the drain end of the transistor, producing the signal at 25 MHz. The bandwidth of the amplifier must be sufficient to ensure that the output is stable.

SG-8002CE 25.0000M-PCMB is an ideal product providing stable frequency output even in harsh environment which requires high performance. It educes power consumption manual adjustment, enables precise frequency setting, and it is suitable for end-products where environmental factors, such as temperature and humidity, have significant effects on the system’s performance. SG-8002CE 25.0000M-PCMB is available from a range of manufacturers in an extremely small package size. It is designed to reduce overall system cost and improve performance in many applications.
