MPC99J93AC is part of a family of clock generator products known as the Crystal Free Clock Generator (CFCG). The family includes three distinct product architectures, a classic Sine Wave, a proprietary Quadrature Modulated Sine Wave (QMSW) and a PLL-based Multi-Phase Clock Direct Digital Synthesizer (MDDS). Within the CFCG family there is the MPC99J93AC, offering a low jitter, high stability clock generator ideal for use in communications, radar, and military applications.

The MPC99J93AC is a multi-phase clock generator that utilizes a proprietary PLL-based frequency synthesizer, known as the Multi-Phase Clock Direct Digital Synthesizer (MDDS). This technology combines the benefits of a traditional PLL and DDS architecture, allowing a wide range of clock synthesizer frequencies to be generated. The MPC99J93AC is particularly well-suited for military applications such as DC generators, navigation systems, and avionics.

The MPC99J93AC features a wide variety of options, such as an adjustable operating frequency range of 1 MHz to 900MHz, an adjustable output phrase range of 0.5 degrees to 180 degrees, a high programmable dynamic range and adjustable internal/external parameters. Additionally, the MPC99J93AC features an extended operating temperature range of -40C to +85C, making it suitable for extreme temperature applications.

The MPC99J93AC utilizes a combination of phase locked loop (PLL) and direct digital synthesizer (DDS) techniques in order to generate its high stability, low jitter clock signal. The signal is generated by first programming the required parameters into the device, which includes the desired operating frequency and the number of clock phases. Once these parameters are set, the device uses a programmable PLL to generate the signal clock signal. The signal is then output from the device, and passed through a low pass filter to remove any unwanted frequencies. Finally, the output is adjusted to the desired phase range through the utilization of a DDS technology.

This combination of PLL and DDS technologies allow the MPC99J93AC to generate signals with very low jitter and high stability, suitable for use in many frequency timing applications, such as communications, radar, and military applications. The device offers excellent features such as adjustable operating frequency, wide dynamic range, and extended temperature range, making it one of the most versatile options in the CFCG family.
