The ZL40221 is an LVDS clock fanout buffer with six output clock drivers capable of operating at frequencies up to 750MHz.
The ZL40221 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40221 can accept DC coupled LVPECL or LVDS and 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 ZL40221 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.
Additional Features
Low additive jitter of 165fs RMS
Input - LVPECL, LVDS, CML, HCSL, LVCMOS
Glitch-free switching of references
On-chip input termination and biasing for AC coupled inputs
Six precision LVDS outputs
Operating frequency up to 750 MHz
Option for 2.5V or 3.3V power supply
Current consumption of 97 mA
On-chip Low Drop Out (LDO) Regulator for superior power supply rejection
