ZL40212 Precision 1:2 LVDS Fanout Buffer
ZL40213 Precision 1:2 LVDS Fanout Buffer with On-Chip Input Termination
Overview
The ZL40212/ZL40213 are LVDS clock fanout buffers 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 or AC coupled LVPECL, LVDS, CML or HCSL input signals; single ended input signals can also be accepted. The ZL40213 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40213 can accept DC or AC coupled LVPECL and LVDS input signals, AC coupled CML or HCSL input signals, and single ended signals.
The ZL40212/ ZL40213 are designed to fanout 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.
