The MAX9380 is a high-precision clock distributor that uses a 2:1 multiplexer with single-ended inputs and differential outputs. It has low part-to-part skew and propagation delay. It is selected by a single select input, and the select and data inputs have internal pull-down resistors that ensure a low default state if they are left open.
The MAX9380 selects one of two single‑ended inputs and converts it to a differential LVPECL or LVECL output. It operates from a +3.0 V to +3.8 V supply (LVPECL) or –3.0 V to –3.8 V (LVECL) and includes internal pulldown resistors for a defined low default state.
Typical applications include precision clock distribution, DSLAMs, base stations and test equipment. The device is offered in 8‑pin UMAX and SO packages and is pin‑compatible with the MC10EP58.
