EV2995-10

The G2995 evaluation board can be used immediately in either a static test environment to check functionality or in a memory termination scheme on a motherboard. In either implementation the following steps should be taken to ensure correct operation.

1. Correct leads from the evaluation board. The board layout has been designed to allows sockets to be directly soldered.

2. AVIN and PVIN should be connected to a 2.5V power supply.

3. The VDDQ input provides the internal divide by two reference voltage. Both VREF and VTT will track this internal voltage, nominally a 2.5V will be applied.

4. The VREF pad is the output for the VREF from the G2995 after being bypassed by a ceramic capacitor.

This can be connected either to a multi-meter for confirmation or directly to the memory controller and DIMMS.

5. The remaining two pads are for the force and sense leads of the VTT output. These should be connected directly to the termination plane or a multi-meter if interested in verification. The output will be regulated where the VSENSE leads connect to the VTT leads permitting the connection to a motherboard without suffering from large resistance drops.
