This datasheet also covers the G2999-GlobalMixed variant, as both devices belong to the same ddr termination regulator family and are provided as variant models within a single manufacturer datasheet.
General Description
The G2998/G2999 is a 3A sink/source tracking termination regulator.
TEMP.
Key Features
Support and DDR I (1.25VTT), DDR II (0.9 VTT) , DDR III (0.75 VTT) , and DDR IIIL (0.675VTT) Requirements.
Input Voltage Range: 3V to 5.5V.
VTT_IN Voltage Range: 1.2V to 3.6V.
Requires Only 20µF Ceramic Output Capacitance.
VTT Pulled Low by 2kΩ Resistor in Stand-By
Mode (G2998 version).
VTT Tri-State in Stand-By Mode
(G2999 version).
Integrated Divider Tracks 1/2 VDDQ for Both
VTT and VREF.
