Description
AI
The ZL40227 is an LVDS clock fanout buffer with eight output clock drivers capable of operating at frequencies up to 750 MHz.
The ZL40227 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40227 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 ZL40227 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.
