DDR5 client clock driver for high performance PCs
Rambus has announced 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.
“As advanced technologies first developed for the data center proliferate to the client space, increasingly powerful PCs will take gaming, content creation and AI to new levels,” said Rami Sethi, SVP and general manager of Memory Interface Chips at Rambus. “This new DDR5 Client Clock Driver is the latest addition to our growing line up of chip offerings that enable breakthrough memory performance across the computing landscape, and bring more value to our customers.”
Features of the Rambus Clint clock driver include:
- 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 of 1.1-V +6%/-3%.
In addition to the CKD, Rambus DDR5 memory interface chips include Gen1 to Gen4 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 yield for server and client DIMMs.
