CDCE913

The CDCE913 is a high-performance clock synthesizer and jitter cleaner designed by Texas Instruments for precision timing applications. It supports up to 8 differential outputs with programmable frequency synthesis, enabling flexible clock distribution in complex system designs. The device features a wide input frequency range from 10 MHz to 500 MHz, allowing compatibility with various reference sources including crystal oscillators and external clocks. Core functionality includes integrated phase-locked loops (PLLs) that provide low-jitter clock generation, essential for high-speed data converters, FPGAs, and communication systems. The CDCE913 offers configurable output frequencies using a fractional-N PLL architecture, which allows fine-grained frequency control without requiring external components. Each of the eight outputs can be individually programmed for voltage level (LVPECL, LVDS, or HCSL), making it suitable for diverse interface standards across different IC families. One of its key advantages is superior jitter performance—typically below 250 fs RMS—ensuring signal integrity in high-bandwidth applications such as 5G infrastructure, radar systems, and test equipment. The device also incorporates advanced power management features, including dynamic power-down modes for individual outputs, reducing overall system power consumption during idle periods. The CDCE913 integrates a comprehensive set of diagnostic functions, including real-time monitoring of lock status, temperature compensation, and fault detection, enhancing reliability in mission-critical environments. Its I²C-compatible serial interface simplifies configuration and runtime adjustments, enabling software-controlled clock management in automated test and deployment scenarios. Designed for industrial and commercial temperature ranges (-40°C to +85°C), the CDCE913 operates reliably in harsh environments common in telecommunications and aerospace applications. It comes in a compact 48-pin QFN package, optimizing PCB space while maintaining excellent thermal performance. With support for multiple reference inputs and redundancy options, it provides robustness against clock source failures, crucial for systems requiring continuous operation.
