The ZL40201 is a precision 1:2 LVPECL fanout buffer designed for high-performance clock distribution applications. It features two identical LVPECL output drivers capable of operating at frequencies up to 750 MHz. The device accepts both differential and single-ended input signals, including LVPECL, LVDS, CML, HCSL, and LVCMOS, with on-chip input termination for DC and AC coupled inputs. An internal linear power supply regulator enhances power supply rejection, contributing to its ultra-low additive jitter of 40 fs. The ZL40201 operates from a 2.5 V or 3.3 V power supply with a core current consumption of 49 mA and is rated for an industrial temperature range of -40¬8C to +85¬8C. This buffer is suitable for applications in wired communications, clock trees, and high-performance microprocessor clock distribution.
The ZL40201 is an LVPECL clock fan out buffer with two identical output clock drivers capable of operating at frequencies up to 750MHz.
The ZL40201 provides an internal input termination network for DC and AC coupled inputs; optional input biasing for AC coupled inputs is also provided. The ZL40201 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 ZL40201 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.
