ZL40214LDF1

Overview

The ZL40214LDF1 is a precision 1:4 LVDS fanout buffer manufactured by Microchip Technology. It accepts differential or single-ended inputs including LVPECL, LVDS, CML, HCSL, and LVCMOS, providing four identical LVDS outputs. The device operates at frequencies up to 750 MHz with an ultra-low additive jitter of 92 fs RMS at 750 MHz. It supports 2.5 V or 3.3 V power supplies via an on-chip LDO regulator, consuming 61 mA. Packaged in a 16-pin QFN (3x3 mm), it functions within the -40°C to +85°C industrial temperature range.

Feature Summary

• Accepts multiple input formats: LVPECL, LVDS, CML, HCSL, and single-ended CMOS
• Four precision LVDS outputs operating up to 750 MHz
• Ultra-low additive jitter of 92 fs RMS at 750 MHz
• On-chip LDO regulator for superior power supply noise rejection

Applications

• General purpose clock distribution
• Low jitter clock trees
• PCI Express generation 1/2/3 clock distribution
• Wired communications: OTN, SONET/SDH, GE, 10 GE, FC, and 10G FC
• High performance microprocessor clock distribution

Procurement Notes

Verify the ordering suffix 'F1' corresponds to the tape and reel packaging format. Confirm the specific voltage mode (2.5V or 3.3V) required for the application design. Ensure PCB layout adheres to the recommended decoupling guidelines using 10 µF and 0.1 µF capacitors to maintain optimal jitter performance.

Selection Notes

Select this component when a low-jitter 1:4 fanout solution is required for LVDS loads. It is suitable for designs needing flexibility in input signal types such as CML or HCSL. Consider the 16-pin QFN package constraints and thermal characteristics if high ambient temperatures are expected. Verify that the 750 MHz maximum frequency meets the system clock requirements.
