Programmable timers and oscillators are electrical circuits that provide a mathematical basis for making decisions regarding whether to perform a certain action or not. These circuits are available in a variety of configurations, ranging from simple triggering of a switch or LED to more advanced sequencing of commands or machine codes. The 8N4SV75BC-0154CDI is one such circuit of programmable timers and oscillators.

The 8N4SV75BC-0154CDI is a clock oscillator manufactured by MCM Electronics. It is a low-phase noise 8-PIN IC with a frequency range from 8 KHz to 40 MHz. The circuit is designed to be programmable in both the frequency and duty cycle for accurate setpoint indication, precise clock generation and precise pulse width modulation. With its low phase noise, it can be used in a variety of applications such as frequency synthesisers, precise oscillators, TV/FM receivers, precision clocks, PWM and servo-controllers.

The module is preset to 8KHz to 40MHz with a center tuning frequency of 22.0MHz. The duty cycle is set at a 50/50 balance with a short delay line. It is an LVCMOS logic device which enables direct connection to the logic supply and can be operated off of a single 3-5V supply. It features TTL compatible output and an enable/disable logic input for controlling the output. The 8N4SV75BC-0154CDI is also RoHS and WEEE compliant.

The 8N4SV75BC-0154CDI module incorporates a phase locked loop technique (PLL) to generate an output frequency that accurately follows an input reference signal. The PLL compares the phase of the output with the input reference signal, and when the two are out of phase, it adjusts the output frequency by changing the gain of the loop filter until the two signals are exactly in phase. This allows the loop to maintain a constant output frequency despite changes in parameters such as temperature and supply voltage.

In addition to its PLL, the 8N4SV75BC-0154CDI also contains a timer which is used to control the output. The timer is set to a certain period during which the output stays in one state before flipping to the other. This time period is adjustable and is used to create the duty cycle. For example, if the timer is set to one second, then the output will stay in one state for one second before flipping to the other for one second and then repeating. The duty cycle can be adjusted by changing the length of the timer period.

The 8N4SV75BC-0154CDI is an excellent choice for those that need a reliable and accurate clock oscillator. It is a feature-rich product that is both RoHS and WEEE compliant, making it suitable for a wide range of applications such as frequency synthesisers, precise oscillators, TV/FM receivers, precision clocks, PWM and servo-controllers. With its low phase noise, it can be used to generate precise and reliable signals, making it an ideal choice for those who need a high-accuracy, reliable clock oscillator.
