RT2568 - DDR Termination Regulator

Datasheet Summary

Description

The RT2568 is a sink/source tracking termination regulator.

It is specifically designed for low-cost and low-external component count systems.

Features

  • required to power the DDRIII and Low Power DDRIII / DDRIV VTT bus termination according to the JEDEC specification. In addition, the RT2568 provides an open-drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR.

Reference Sample & Design Buy ® RT2568 DDR Termination Regulator General Description The RT2568 is a sink/source tracking termination regulator. It is specifically designed for low-cost and low-external component count systems. The RT2568 possesses a high speed operating amplifier that provides fast load transient response and only requires a minimum 10μF x 3 ceramic output capacitor. The RT2568 supports remote sensing functions and all features required to power the DDRIII and Low Power DDRIII / DDRIV VTT bus termination according to the JEDEC specification. In addition, the RT2568 provides an open-drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications.
