The MAX3872ETJ+ is a Clock/Timing – Application Specific designed to meet a variety of high-performance timing application requirements. The MAX3872ETJ+ is a member of the MAX3872ETJ family of programmable frequency synthesizers, which can be used to generate frequency-agile signals from a single reference input. The programmable frequency synthesizer consists of multiple delay and programmable-output multiphase PLLs, whose frequency and phase responses are programmable. In addition, an external trigger input offers the ability to change frequencies quickly in order to meet the requirements of high-speed, real-time control and imaging applications.

The MAX3872ETJ+ can generate multiple low-jitter, multiphase clocks from a single reference input, allowing the user to customize the multi-phase clock outputs to meet specific application requirements. The MAX3872ETJ+ also features an on-board programmable frequency synthesizer, which is capable of outputting frequency-agile signals over a wide range of frequencies.

The MAX3872ETJ+ uses a Voltage Controlled Oscillator (VCO) to generate a variable frequency or phase output. The output of the VCO is programmed by the user through an on-board programmable memory, which can be programmed via a serial interface. The output of the VCO is then fed through a programmable loop filter to the phase programmable outputs. The programmable loop filter is used to modulate the frequency output such that it can be tuned for different applications. The programmable loop filter also allows the user to adjust the phase response of the output for specific applications.

The MAX3872ETJ+ also features a programmable frequency synthesizer architecture which includes multiple delay lines and programmable phase detectors. These components work together to generate low-jitter signals from a single reference clock. The programmable phase detectors can be programmed to generate phase-agile signals for applications such as time code synchronization and time division multiplexing.

The MAX3872ETJ+ also features an external clock input. The external clock input can be used to synchronize the clock outputs to an external signal. This feature allows the user to utilize an external clock signal to synchronize the clock outputs to an external system or use the external clock to drive the synthesizer.

The MAX3872ETJ+ also features an on-board programmable Power Management Unit (PMU). This programmable PMU can be used to configure the clock outputs for a variety of dynamic power management applications. The PMU allows the user to program the clock outputs for a variety of power management schemes, such as frequency-scaling, voltage-scaling, and dynamic voltage and frequency scaling (DVFS).

The MAX3872ETJ+ is a very high performance clock/timing application specific device, and it is well suited for a variety of high-performance, frequency-agile timing applications. The MAX3872ETJ+ is an ideal solution for applications such as digital system clocks, communication systems, timing controllers, test and measurement equipment, consumer electronics, and automotive systems.
