Product Overview: CDCV857 from Texas Instruments

The CDCV857 is a high-performance, low-skew clock driver from Texas Instruments, designed to distribute high-speed signals in clock distribution applications. It features a two-input multiplexer and a bank of four identical output drivers. These output drivers have 3-state capabilities which provide the flexibility to go into a high impedance state, thus allowing for additional clock management strategies.

This device is particularly well-suited for distributing high-speed signals across PCBs and within systems due to its low skew properties, ensuring that clock signals arrive at their destinations simultaneously, a critical feature for maintaining data coherence and timing in high-speed digital systems. The CDCV857 is designed to support clock distribution for a variety of applications, including servers, telecommunications, workstations, and other network equipment.

Key Features:

• Low Skew: The CDCV857 provides extremely low skew (< 250 ps) between outputs, ensuring synchronous signal distribution.
• High Speed: Capable of operating at high frequencies, this clock driver maintains signal integrity across a range of operational conditions.
• Multiple Outputs: With four outputs, the CDCV857 can drive multiple loads while maintaining a low skew rate.
• 3-State Outputs: The inclusion of 3-state output capability allows for disabling the outputs, which is useful for testing or multiplexing different clock signals.
• Versatility: It offers a wide range of operating voltages from 3.3V to 5V, which makes it suitable for various logic families and system requirements.
• Thermal Protection: The device is equipped with over-temperature protection, enhancing its reliability and longevity.

The CDCV857 is available in a compact surface-mount package, making it easy to integrate into a variety of circuit designs. Its robust feature set and high performance make it an excellent choice for designers looking to implement precise clock distribution schemes in their digital systems. Texas Instruments provides comprehensive technical support and documentation, ensuring that integrating the CDCV857 into your design is as seamless as possible.
