SIT9005ACL1D-28EN

Programmable Oscillators

The SIT9005ACL1D-28EN is a programmable oscillator and frequency synthesizer, designed to meet the requirements of frequency-hopping spread spectrum (FHSS). It is typically used to provide a constant radio frequency signal source for communication systems.

This oscillator can be programmed to generate outputs of different frequencies within a range of 5-220 MHz. It is equipped with a wide range of features such as programmable output amplitudes, and dynamic frequency control (DFC). In addition, it has low phase noise, high reliability, and excellent phase noise performance.

The SIT9005ACL1D-28EN consists of a voltage controlled oscillator (VCO), a phase-locked loop (PLL) and a programmable frequency divider. The VCO produces the carrier frequency, which is then fed into the PLL for frequency division. The programmable frequency divider is used to divide the output of the PLL and generate the desired frequency. The output of the divider is then fed back to the VCO for correction and synchronization, thus creating a stable output signal.

This device is suitable for applications such as digital data communications, radio transmitters/receivers, navigation systems, radios, satellite TV systems and so on. It offers many advantages such as low cost, small size, low power consumption and high performance.
