CDCV857BIDGGR

CDCV857BIDGGR Description

The CDCV857BIDGGR 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. It features a 1:10 input-to-output ratio with differential input and output capabilities, ensuring low-jitter signal integrity. Packaged in a 48-pin TSSOP and available in tape & reel (TR), it is optimized for surface-mount assembly. Although marked as obsolete, it remains a reliable choice for legacy designs requiring stable clock distribution.

CDCV857BIDGGR Features

• PLL with Bypass Mode: Enables flexible clock synchronization with minimal phase noise.
• Differential I/O: Supports LVDS/LVPECL compatible signals for noise immunity in high-speed systems.
• 1:10 Fanout: Distributes a single clock signal to 10 outputs with precise timing alignment.
• Wide Frequency Range: Operates up to 200MHz, ideal for telecom, networking, and computing applications.
• Low-Voltage Operation: 2.3V–2.7V supply range reduces power consumption in portable and embedded systems.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Surface-Mount (TSSOP-48): Compact footprint for space-constrained PCB layouts.

CDCV857BIDGGR Applications

This clock driver excels in systems requiring low-jitter, high-fanout clock distribution, such as:

• Telecommunications Equipment: Synchronizing base stations and network switches.
• Data Centers: Clock tree management in servers and storage systems.
• Test & Measurement: Precision timing for oscilloscopes and signal analyzers.
• Embedded Computing: Clocking FPGAs, ASICs, and multi-processor systems.
  Its differential signaling minimizes EMI, making it ideal for noise-sensitive environments.

Conclusion of CDCV857BIDGGR
