CDCDB400RHBR Description

The CDCDB400RHBR from Texas Instruments is a high-performance 1:4 clock buffer designed for precision timing applications. This surface-mount IC operates within a 3V to 3.6V supply range and supports HCSL (High-Speed Current Steering Logic) inputs and outputs, ensuring low-jitter signal distribution. With a maximum frequency of 250 MHz, it is optimized for high-speed data transmission systems. The device features differential input/output capability, enhancing noise immunity and signal integrity in demanding environments. Packaged in a 32-VQFN format and supplied in Tape & Reel (TR), it is ideal for automated assembly processes.

CDCDB400RHBR Features

• 1:4 Clock Distribution: Provides precise signal replication for multi-channel systems.
• Differential I/O (HCSL): Ensures robust performance in noisy environments.
• Wide Voltage Range (3V–3.6V): Compatible with common logic levels.
• 250 MHz Max Frequency: Suitable for high-speed applications.
• Surface-Mount (32-VQFN): Compact footprint for space-constrained designs.
• Moisture Sensitivity Level (MSL 1): Unlimited shelf life, simplifying inventory management.
• RoHS Status: Not applicable, but complies with industry standards for reliability.

CDCDB400RHBR Applications

This clock buffer excels in applications requiring low-jitter, high-fanout clock distribution, such as:

• Networking Equipment: Synchronization in switches, routers, and servers.
• Telecommunications: Base stations and optical transport systems.
• Data Centers: Clock tree management for FPGAs, ASICs, and memory interfaces.
• Test & Measurement: Precision timing for oscilloscopes and signal analyzers.
  Its differential signaling makes it ideal for high-speed serial links (PCIe, SATA, Ethernet), while its low power consumption suits portable and embedded systems.

Conclusion of CDCDB400RHBR

The CDCDB400RHBR stands out as a high-reliability, low-jitter solution for clock distribution in advanced electronic systems. Its HCSL support, differential I/O, and 250 MHz capability make it superior to generic buffers, particularly in noise-sensitive, high-speed designs. With Texas Instruments' quality assurance and a surface-mount package, it is a top choice for engineers designing networking, telecom, and data center hardware. For applications demanding precision timing with minimal skew, this IC delivers unmatched performance.
