CDCFR83 is a Direct Rambus clock generator from Texas Instruments that provides a 533 MHz clock source for Direct Rambus memory systems for an 1066 MHz data transfer rate. CDCFR83 can also synchronize the Rambus channel clock domain with an external system clock or processor clock. CDCFR83 employs three power operating modes to minimize power consumption for mobile applications and other power-sensitive applications. CDCFR83 is powered by a single 3.3 V supply and consumes 120 mW (typical) and is packaged in a Shrink Small-Outline Package (DBQ). CDCFR83 supports frequency multipliers of 4, 6, 8, 16/3, does not require external components for PLL, supports independent channel clocking, and has spread spectrum clocking tracking capability to reduce EMI. CDCFR83 is designed for use with TI's 133 MHz clock synthesizers CDC924 and CDC921. Its cycle-to-cycle jitter is less than 40 ps at 533 MHz. CDCFR83 has been certified by Gigatest Labs to exceed the Rambus DRCG validation requirement and supports an industrial temperature range of -40°C to 85°C.
