General Description

The NJW4118 is a sink/source (±2A) termination regulator for DDR-SDRAM. The NJW4118 contains a high-speed operational amplifier that provides excellent transient response. The NJW4118 can configure the two patterns of VREF +VTT output or VTT standalone output by change of wiring. Even if VREF is generated outside, VTT is able to subordinate to VREF because there is VREF_IN Pin. When using at VTT standalone, it is possible to contribute to low power consumption because VREF circuit can be completely stopped. Regarding the EN function, each output becomes as the following status: VREF is Active and VTT is OFF (Discharge) at EN=Low.
