Description

The ZL40225 is an LVPECL clock fan out buffer with two input and eight output clock drivers capable of operating at frequencies up to 750MHz. The ZL40225 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40225 can accept DC or AC coupled LVPECL and LVDS input signals, AC coupled CML or HCSL input signals, and single ended signals. A pin compatible device with external termination is also available. The ZL40225 is designed to fan out low-jitter reference clocks for wired or optical communications applications while adding minimal jitter to the clock signal. An internal linear power supply regulator and bulk capacitors minimize additive jitter due to power supply noise. The device operates from 2.5V+/-5% or 3.3V+/-5% supply. It's operation is guaranteed over the industrial temperature range -40°C to +85°C.
