The CDCR83A Direct Rambus(TM) Clock Generator from Texas Instruments is designed to provide a 400-MHz differential clock source for Direct Rambus memory systems, supporting an 800-MHz data transfer rate. It features fail-safe power-up initialization and synchronizes the clock domains of the Rambus channel with an external system or processor clock. The device operates from a single 3.3-V supply and consumes approximately 120 mW at 300 MHz, making it suitable for power-sensitive applications. This clock generator supports multiple frequency multipliers (4, 6, 8, 16/3) and does not require external components for the phase-locked loop (PLL). It allows for independent channel clocking and includes spread spectrum clocking capabilities to reduce electromagnetic interference (EMI). The CDCR83A is characterized for operation over an industrial temperature range of -40¬8C to 85¬8C and is packaged in a shrink small-outline package (DBQ). Cycle-to-cycle jitter is less than 50 ps at 400 MHz, and the product has been certified to exceed Rambus DRCG validation requirements.
