ZL40213LDF1

Overview

The ZL40213LDF1 is a clock buffer from the miSmart series, manufactured by Microchip Technology. It features one input and two outputs with a maximum output frequency of 750 MHz. The device operates within a supply voltage range of 1.35 V to 3.465 V and supports LVCMOS output types. It is housed in a 16-QFN package (3x3 mm) with an exposed pad. The component functions as a fanout buffer for clock distribution applications.

Feature Summary

• Provides low skew and ultra-low added jitter performance for precise clock distribution
• Integrates with miClockSynth synthesizers to create simplified and reliable clock trees
• Supports LVCMOS output configurations for standard logic interface compatibility

Applications

• PCI Express clock distribution systems
• High-speed data converter clocking
• FPGA and ASIC clock tree generation

Procurement Notes

Verify the specific ordering suffix LDF1 to ensure the correct tape-and-reel packaging quantity of 4000 units. Confirm that the 16-VFQFN package variant matches your PCB footprint requirements. Check for moisture sensitivity level indicators on the reel label to ensure proper storage conditions prior to soldering. Validate that the device revision aligns with your design's timing constraints.

Selection Notes

Select this component when a single differential or single-ended input must be distributed to two LVCMOS loads with minimal jitter degradation. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Verify that the 750 MHz maximum frequency capability exceeds your system's clock requirements. Consider the 1.35 V to 3.465 V supply voltage flexibility for mixed-voltage designs.

Part Context

This part belongs to the ZL402x family of clock fanout buffers, which includes various output combinations and I/O types such as LVPECL and LVDS. The miSmart series distinguishes itself by offering integrated solutions for clock generation and distribution. The ZL40213 specifically addresses the need for simple 1-to-2 fanout buffering in high-performance digital systems.

Replacement Considerations

Consult official substitution lists for direct pin-compatible alternatives within the ZL402x family. Verify electrical parameter equivalence for frequency and jitter if cross-referencing with other manufacturers' components.
