The ZL40212 is an LVDS clock fanout buffer with two identical output clock drivers capable of operating at frequencies up to 750MHz.
Inputs to the ZL40212 are externally terminated to allow use of precision termination components and to allow full flexibility of input termination. The ZL40212 can accept DC coupled LVPECL or LVDS and AC coupled LVPECL, LVDS, CML or HCSL input signals; single ended input signals can also be accepted. A pin compatible device with internal termination is also available.
The ZL40212 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. Its operation is guaranteed over the industrial temperature range -40°C to +85°C.
Additional Features
Low additive jitter of 92 fs RMS
Accepts differential or single-ended input: LVPECL, LVDS, CML, HCSL, LVCMOS
Two precision LVDS outputs
Operating frequency up to 750 MHz
Options for 2.5 V or 3.3 V power supply wit6h current consumption of 44 mA
On-chip Low Drop Out (LDO) Regulator for superior power supply noise rejection
