Overview
Description
The RG5R188 (MRCD) is a registering clock driver used on MCR DIMMs. It's primary function is to buffer the Command/Address (CA) bus, chip selects, and clock between the host controller and the DRAMs. It also creates a BCOM bus which control the data buffers.
Features
- MCR DIMM server speeds up to 8800MT/s
- Supports power-down modes to conserve server power
- Supports 1 rank per Pseudo-channel in x4 mode and 2 ranks per Pseudo-channel in x8 mode
- Supports SDP, DDP, 3DS DRAM types
- Provides access to internal control words for configuring device features and adapting to different system applications
- I3C sideband access for asynchronous register access control
- BCOM data buffer control
- Loopback and pass-through modes
- Package: 8.7 × 13.5 mm, 240-FCBGA
