DDR5 clock driver handles 7200 MT/s
A DDR5 registering clock driver (RCD) from Rambus, the RCD4-GA0A boosts data rates to 7200 MT/s, a significant increase over DDR5 devices operating at 4800 MT/s. Intended for registered DIMMs, the driver chip can accelerate performance in generative AI and other advanced data-center workloads.
The RCD4-GA0A supports a clock rate of up to 3.6 GHz, corresponding to its data rate of up to 7200 MT/s. It also accommodates double data rate (DDR) and single data rate (SDR) buses, providing clocks and command/address (CA) signals to the DRAM devices in registered DIMMs. The driver supports two independent subchannels per registered DIMM and two physical ranks per subchannel. For high-capacity registered DIMMs, the driver supports up to 16 logical ranks per physical rank.
Rambus began sampling the RCD4-GA0A registering clock driver to major DDR5 memory module manufacturers during the fourth quarter of 2023. The company also offers a serial presence detect (SPD) hub and temperature sensor for use with its DDR5 RCDs.
