CDC6C

The CDC6C is a high-performance clock distribution buffer manufactured by Texas Instruments, designed to provide precise and reliable signal routing in complex digital systems. It supports a wide input frequency range from 10 MHz to 250 MHz, enabling compatibility with various clock sources such as crystal oscillators, PLLs, and other timing devices. The device features low jitter performance—typically less than 1 ps RMS—which ensures minimal timing uncertainty across multiple outputs, making it ideal for applications requiring high signal integrity. This IC offers six independent output channels, each capable of driving up to 20 mA of current, allowing it to interface directly with a broad range of logic families including TTL, CMOS, and LVCMOS. Its differential inputs and outputs support both single-ended and differential signaling modes, enhancing flexibility in system design. Additionally, the CDC6C includes internal power-on reset functionality that guarantees a known state upon startup, reducing the risk of metastability or undefined behavior during system initialization. Designed for operation over a wide temperature range—from -40°C to +85°C—the CDC6C is suitable for industrial, automotive, and telecommunications environments where reliability under harsh conditions is critical. It operates on a single 3.3 V supply, consuming minimal static power (typically 75 mW), which contributes to energy-efficient system designs without compromising performance. The CDC6C is commonly used in high-speed data acquisition systems, FPGA and ASIC clocking architectures, memory interfaces, and communication equipment such as routers and switches. Its ability to distribute a single clock source to multiple destinations with minimal skew and jitter makes it a key component in systems demanding synchronized operations across multiple chips or subsystems. Moreover, its robust EMI immunity and low electromagnetic emissions make it appropriate for use in noise-sensitive environments like medical imaging or test-and-measurement instruments. Texas Instruments integrates advanced process technology into the CDC6C, ensuring high manufacturing yield and long-term availability. The device is available in a compact 28-pin TSSOP package, facilitating easy integration into space-constrained PCB layouts. With comprehensive documentation, reference designs, and support tools provided by TI, engineers can rapidly implement the CDC6C into their designs while minimizing development time and risk.
