Rambus has announced the availability of its DDR5 Client Clock Driver (CKD), enabling up to 7200 MT/s for high-performance PCs.
Rambus DDR5 CKD Technology Aims At Taking Memory Capabilities On Next-Gen High-Performance PCs To New Heights, Offering Up To 7200 MT/s Speeds
[Press Release]: Rambus Inc., a premier chip and silicon IP provider making data faster and safer, today announced the availability of its DDR5 Client Clock Driver (CKD) for next-generation, high-performance desktops and notebooks. The Rambus DDR5 CKD and SPD Hub are part of a new client memory interface chip product offering that brings server technology advancements to the client market.
Leveraging over 30 years of memory system expertise, the Rambus DDR5 CKD enables new client DIMMs (CSODIMMs and CUDIMMs) to operate at state-of-the-art data rates of up to 7200 Megatransfers per second (MT/s) and deliver breakthrough performance in next-generation PCs.
Features of the DDR5 CKD
- Receives up to four differential input clock pairs
- Provides up to four differential output clock pairs
- Supports Single PLL, Dual PLL, and PLL Bypass modes
- Supports clock frequencies from 1600 to 3600 MHz (DDR5-3200 to DDR5-7200)
- Down-bin operations from 990 to 1050 MHz
- Supports test mode operation from 140 to 1400 MHz
- Supports I2C/I3C Sideband Bus interface for device configuration and status monitoring
- Asynchronous reset input
- Operational at VDD = 1.1V +6% / -3%
In addition to the CKD, Rambus DDR5 memory interface chips include Gen 1 to Gen 4 RCDs, Power Management ICs (PMICs), Serial Presence Detect (SPD) Hubs, and Temperature Sensors for leading-edge servers. As data rates continue to rise, signal integrity (SI) and power integrity (PI) management become increasingly vital. With over 30 years of high-performance memory experience, Rambus is renowned for its SI/PI expertise.
This expertise helps enable DDR5 memory interface chips to deliver superior signal integrity and power efficiency at higher yields for server and client DIMMs.
