Intel®'s EV1320 is an ideal source/sink DDR termination converter offering excellent performance with low cost and a tiny solution footprint. EV1320 solutions deliver nearly 2 times efficiency at or below the cost of commonly used VTT LDOs. The VTT converter accepts an input voltage of 0.95 V to 1.8 V. Multiple EV1320 devices may be placed in parallel to support larger DDR memory capacities (higher load requirements). EV1320 is a purpose-built VTT converter solution that complies with JEDEC specifications, in particular tracking accuracy and AC + DC requirements for supporting DDR2/DDR3/QDR and low-power DDR3/DDR4 VTT applications.
