CSPT857DBVG

Application Field and Working Principle for CSPT857DBVG

The CSPT857DBVG is an advanced clock/timing solution designed for application-specific use. It is a fully integrated device, combining both timing control and power management in one unit with the objective to reduce overall system complexity and cost. The CSPT857DBVG is ideally suited for System-on-modules (SoM) and other embedded applications that require precise timing and power management.

Clock/Timing Performance

The CSPT857DBVG provides a 4.24GHz internal clock generator. This allows for the generation of multiple clock outputs with a range from 0 to 6.5 GHz with a resolution of 250ps. These clocks can be configurable to different modes such as spread spectrum, dual channel, and automatic frequency tuning. This ensures the flexibility to meet different application timing needs while minimizing EMI levels.

The device incorporates advanced jitter reduction techniques such as Zero Delay Buffer (ZDB) and Clock Sync Intermediate Frequency (CSIF) functionalities. The maximum jitter requirements for the outputs are typically less than 3ps Integrated Phase Jitter (IPJ) at 4.24GHz output frequency.

Power Management

The CSPT857DBVG integrates advanced power management and control technology to drive multiple voltage rails from a single output. The integrated on-board regulator provides up to five output voltages from a single output and can provide up to 1A of regulated current for each of the output rails. The regulator also incorporates advanced control techniques such as voltage tracking and rate of change limiting to accommodate dynamic power supply inputs.

The device is designed to provide high precision voltage regulation and very low output ripple and noise. This provides for optimal system performance in terms of both power and data transfer timing.

Applications

The CSPT857DBVG is ideally suited for embedded and mobile applications such as system-on-modules (SoM) that require advanced timing and power management solutions. These applications may include digital video, media streaming, computing, storage, networking and communication systems.

Conclusion

The CSPT857DBVG is a fully integrated clock/timing and power solution ideally suited for application specific use. It provides robust, reliable and precise clock/timing solutions with jitter as low as 3ps IPj and precisely regulated power for multiple voltage rails. These capabilities make the device an excellent choice for embedded and mobile applications where precision timing and power management are essential.
