LMH7324: LMH7324

Part Number: LMH7324

In the second paragraph of "Description" (page 1), the first paragraph of "Introduction" (page 9), and Fig 19, LMH7324 with LVDS output is used by setting Vcco = 2.5V.

However, the first line of "Operating Rating" (page 2) highlights that Vccx (where x stands for input, i and output, o) cannot drop below 5V to avoid device breakdown (note 1).

I wonder if Vcco can be set to 2.5V, allowing LVDS output without compromising the device?

    Hi Nicola,

    Thanks for reaching out. I can see how it can be a little confusing. The operating ratings table states that VCCx - VEE cannot drop below 5V, as in the difference between the positive supply voltage and negative supply voltage cannot be below 5V. Therefore, you can set VCCO to 2.5V as long as VEE is set to some negative potential that will bring the difference between 5V -12V. In figure 19, VCCO is 2.5V but VEE is -5V, which makes it a valid condition. Keep in mind output levels are referenced from VCCO.
