The RRG5004 (Gen 4 RCD) is a registering clock driver used on DDR5 RDIMMs. It supports DDR5 server speeds up to 7200 MT/s. Its primary function is to buffer the Command Address (CA) bus, chip selects, and clock between the host controller and the DRAMs. * Dual-Channel Design: Operates independently with shared common logic such as clocking, enhancing performance and reliability. * High-Speed Support: Achieves speeds up to 7200 MT/s, catering to the demands of modern server environments. * Versatile Compatibility: Supports both x4 and x8 DRAM configurations, providing flexibility for various applications. * I3C Bus Interface: Facilitates sideband communication with the CPU or motherboard Baseboard Management Controller (BMC), ensuring smooth operations and management. * Efficient Data Handling: Each channel features a 7-bit double data rate CA bus input, single parity input, two chip-select inputs, and produces two copies of 14-bit single data rate CA bus outputs and chip-select outputs. * Integrated Clock Management: Common clock input and PLL with separate clock outputs for each DRAM channel, optimizing synchronization and performance.
