Termination Regulator (DDR2 TR)

Overview

DDR2 TR module, is a sink/source Double Data Rate Termination Regulator, specifically designed to meet the JEDEC SSTL_18 specifications, providing a tightly regulated VTT termination voltage, within ± 40mV, for bus termination. The Termination Regulator module includes an output signal to monitor the Reference Voltage which can be set externally by using two external resistors. No external filters are needed. In addition, an Enable command can be used to select the Suspend-to-RAM mode for low power consumption. The DDR2 TR module supports DDR1 and DDR2 memory applications and provides a remote sensing function.

The design has been optimized in order to be thermally efficient ensuring a fully operational module in most part of the applications. Offered in SOP and BGA packages for high resistance SMT assembly and for withstanding harsh thermal and mechanical environments.

DDR2 TR modules are Radiation Hardened by Design, compact and suitable for any space application such as commercial or scientific GEO stationary missions, Earth observation, navigation, manned space vehicles and deep scientific exploration.
