Programmable Oscillators, like SIT1602AIB8-28S, are relatively hardware-and-software-based frequency control components which can quickly and easily control the frequency and phase of multiple oscillators in one phase-locked loop. Each phase-locked loop consists of two roots: an analog phase-locked loop (PLL) and a digital PLL or "DPLL." By combining the two roots, a programmable oscillator can accurately control the frequency of multiple oscillators in one circuit.

The SIT1602AIB8-28S are digital, pulse-width-modulated (PWM) devices which employ a complementary symmetry (CMOS) technology to reduce power consumption and improve performance. These devices provide a programmable pulse width to control the frequency of an oscillator, and utilize an on-chip phase-locked loop (PLL) circuitry to program the output frequency of the oscillator. The SIT1602AIB8-28S is designed to reduce the number of external components, simplify the control circuitry, and increase design flexibility. Its built-in phase-locked loop (PLL) configuration increases its ability to control the output frequency accurately and eliminates the need to manual adjustment. Additionally, it offers excellent RF isolation, enabling it to maintain high frequency accuracy over a wide range of input signals.

The SIT1602AIB8-28S features an update rate of 16 MHz and a minimum pulse width of 28.8 ns. It is capable of generating tightly accurate and adjustable VCO frequencies up to 200 MHz with quadrature outputs. These outputs are then fed back to the PLL to ensure high accuracy and stability of the programmable oscillator. With an adjustable duty cycle range of 25% to 75%, the SIT1602AIB8-28S is capable of extensive frequency tuning depending on the particular application requirements. It also dispenses with the need for external capacitors for compensation due to its low-drift design built into the device.

The SIT1602AIB8-28S programmable oscillator is suitable for a wide array of applications, including cellular networking systems, Wi-Fi connectivity, and gaming devices, as well as for sampling gates, data acquisition, amplifier control, and frequency synthesizers. This device is also frequently employed in test equipment, remote instrumentation, multiplexers, and clock generation schemes. In addition, its low-power consumption, decent accuracy, and fast settling time make it an ideal solution for embedded and portable applications.

In summary, the SIT1602AIB8-28S is an exceptionally efficient and economical programmable oscillator due to its PLL design. Its variable duty cycle, fast update rate and voltage supply capabilities make it an effective solution for various applications need accurate and adjustable frequency control. With its power and performance, it can provide a critical level of frequency control for a wide range of products.
