The SI5338A-B07875-GMR is an application-specific clock manager (ASCM) frequency synthesizer with integrated differential and LVDS output buffers.
It is primarily designed for use in ultra-high performance CCTV (closed-circuit television) cameras, broadcasting and recording applications; but can be used in any application requiring a frequency synthesizer with LVDS outputs.

The SI5338A-B07875-GMR is touted as a one-stop solution for multiple frequency synthesis needs. It has a fast locking time of 20ms, adjustable operating frequency range from 10kHz to 370MHz, and variable output voltages from 0.75V to 3.2V.

The SI5338A-B07875-GMR requires an input reference clock frequency. The reference clock is used to drive the Synthesizer’s synthesizer core which, together with its programmable Dividers, produces an output frequency. The Synthesizer can output this frequency on one differential port, or both (if using LVDS), up to two LVDS ports, and one differential port.

The LVDS port can be used to output a frequency that is different from the one produced by the Synthesizer core. This allows broadcasters and camera professionals to maintain precision over their signal’s frequency and the clock outputs they need. The Synthesizer also contains output logic level control to guarantee proper operation of the LVDS outputs. The output frequency can also be tuned using a programmed input clock frequency.

The SI5338A-B07875-GMR\'s reference clock frequency range is very wide, ranging from 10 kHz to 370MHz - allowing for great flexibility when applying the device for different purposes. This wide frequency range also allows users to set frequencies beyond the frequency of the input reference clock. This means that users are able to adjust the output frequency to the perfect setting for their setup without having to purchase additional parts. Users can also change the output frequency without having to ever change the reference clock.

The SI5338A-B07875-GMR also features integrated phase-locked loops (PLLs), programmable spread-spectrum clock jitter attenuation, and adjustable input pre-dividers. All the features make this frequency synthesizer ideal for applications requiring reliable clock signal accuracy and excellent video signal performance.

In addition to its frequency synthesis functions, the SI5338A-B07875-GMR offers several monitoring and protective features such as a temperature monitor and an adjustable watchdog timer. It also contains an internal EEPROM to store configuration and calibration data. The EEPROM also ensures that the device returns to its original configuration after a power cycle or reset.

The SI5338A-B07875-GMR is a highly capable and reliable frequency synthesizer which can produce a wide range of accurate and precise clock frequencies; making it ideal for use in various CCTV, broadcasting, and recording applications. It also offers adjustable output frequencies, wide-ranging input reference clock frequencies, integrated phase-locked loops and programmable spread-spectrum clock jitter attenuation, as well as temperature monitoring and other protective features, ultimately giving users an all-encompassing solution.
