Frequently Asked Question

Can I tri-state the AD9510 outputs?

Not exactly. The LVPECL channels have both a "safe" and "unsafe" power-down mode. The unsafe mode is essentially tri-state, but care must be taken not to exceed the reverse bias limits on this node or device damage may occur. In the safe power-down mode, the outputs are protected, but not tri-state. The LVDS and CMOS outputs when powered-down are effectively in tri-state.
