DATA BUFFER

With the industry’s largest product portfolio, IDT is the only company

that can provide complete DDR4 and DDR3 chipset solutions for

Enterprise Server memory modules.

• Paired with 4RCD023 for LRDIMM

• Dual 4-bit bidirectional data registers with

differential data strobes

IDT’s DDR4 Registered Clock Driver, Data Buffer and Temp Sensor make up

the industry’s first complete chipset for DDR4 registered dual in-line memory

modules (RDIMMs) and load reduced dual inline memory modules (LRDIMMs).

With DDR4 data rates climbing to 3.2Gb/s and higher, the clear advantages

afforded by RDIMM and LRDIMM as a speed-scalable memory technology are

expected to drive adoption across a broad array of memory-intensive computing

and storage applications.

• 1.2V Vdd operation

• Automatic impedance calibration

• BCOM Parity Checking

• Control register BCW readback

Temp Sensor + EEPROM

• Used in UDIMM, RDIMM, LRDIMM

• Temperature accuracy up to 0.5ꢀC

• 512 byte EEPROM for vendor info

• 1MHz I²C bus

Through flexible I/O control, timing and voltage calibration, and control register

programmability, the IDT DDR4 Registered Clock Driver (4RCD023) and Data

Buffer (4DB0232) enable faster data rates at higher densities on all JEDEC^®

defined DDR4 LRDIMM and RDIMM topologies. DIMM topology configuration

BENEFITS

• All devices are JEDEC^®compliant and meet

stringent requirements for reliability and

application compliance

With a deep knowledge of memory interface chipsets based on successful

chipset introductions for all DDR generations, IDT’s devices will provide reliable

performance for your application.

• Up to 35% DDR4 power savings compared

to DDR3

• EnablesTerabyte DIMM memories

• Parity and CRC for improved data error recovery

• Improved debug and system margining

Applications

Applications requiring deeper memory at higher data rates and lowest power

including enterprise servers, data centers, workstations, storage devices, and

communications.
