CDCV857BDGG Description

The CDCV857BDGG from Texas Instruments is a high-performance PLL-based clock driver designed for precision clock distribution in demanding electronic systems. Operating within a 2.3V to 2.7V supply range, this device supports frequencies up to 200MHz, making it suitable for high-speed applications. Housed in a 48-pin TSSOP package, it features a 1:10 input-to-output ratio with differential input and output capabilities, ensuring low-jitter signal integrity. The integrated PLL with bypass mode enhances flexibility, allowing seamless clock synchronization or direct signal routing.

CDCV857BDGG Features

• PLL with Bypass Mode: Enables low-jitter clock generation or direct signal pass-through for system flexibility.
• Differential I/O: Supports LVDS, LVPECL, or HCSL interfaces, reducing noise susceptibility in high-speed designs.
• Wide Frequency Range: Operates up to 200MHz, ideal for networking, telecom, and computing applications.
• Low Voltage Operation: 2.3V–2.7V supply range optimizes power efficiency in portable and embedded systems.
• Robust Packaging: 48-TSSOP surface-mount package ensures reliable performance in space-constrained layouts.
• Compliance: RoHS3 and REACH compliant, meeting global environmental standards.

CDCV857BDGG Applications

This clock driver excels in systems requiring high-fidelity clock distribution, such as:

• Networking Equipment: Synchronizes timing in switches, routers, and base stations.
• Data Centers: Ensures precise clocking for servers and storage arrays.
• Test & Measurement: Delivers stable signals for oscilloscopes and signal analyzers.
• FPGA/ASIC Systems: Provides low-skew clocks for multi-chip designs.

Conclusion of CDCV857BDGG

The CDCV857BDGG stands out for its PLL flexibility, differential signaling, and high-frequency support, making it a robust choice for clock distribution in mission-critical applications. While now obsolete, its design remains relevant for legacy systems requiring low-jitter, high-performance timing solutions. Engineers should evaluate alternative TI offerings for new designs but can rely on this device for proven performance in existing implementations.
