Forum Post: LM98640 Digital I/O Voltage

$

I am working on a circuit board using LM98640 to interface an FPGA. The datasheet specifies digital supply voltage of 1.8V, but Electrical Characteristics table shows that VIH and VOH min is 2.0V and 1.8V, respectively. Based on the Electrical Characteristics table, the I/O voltage (digital) can't be 1.8V. I suspect it should be 3.3V, but I guess my question is: what FPGA I/Os (1.8V or 3.3V) should the LM98640 interface to? Thanks in advance for any insight/clarification. -Simon
