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. Temperature accuracy up to ±0.5°C 512 byte EEPROM for vendor info 1MHz I2C bus BENEFITS • All devices are JEDEC® compliant and meet stringent requirements for reliability and application compliance • Up to 35% DDR4 power savings compared to DDR3 • Enables Terabyte DIMM memories • Parity and CRC for improved data error recovery • Improved debug and system margining For more information visit: idt.com/DDR4 idt.com/DDR3 idt.com/TempSensor 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 and DRAM information is stored in IDT’s Temperature Sensor EEPROM (TSE2004). 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. Applications Applications requiring deeper memory at higher data rates and lowest power including enterprise servers, data centers, workstations, storage devices, and communications.
