ZL30110LDF1

Overview

The ZL30110LDF1 is a telecom-grade Digital Phase-Locked Loop (DPLL) rate converter manufactured by Microchip Technology. It operates with a maximum frequency of 100 MHz and features a single circuit configuration. The device supports an input-to-output ratio of 2:4, accepting LVCMOS or crystal inputs and providing LVCMOS outputs without differential signaling capabilities. It functions within a supply voltage range of 3.1 V to 3.5 V and is rated for operation between -40°C and +85°C. The component is housed in a 32-VFQFN package with exposed pads, measuring 5x5 mm.

Feature Summary

• Digital Phase-Locked Loop (DPLL) architecture for precise rate conversion
• Supports 2:4 input-to-output frequency ratios
• Maximum operating frequency of 100 MHz
• LVCMOS input and output signal levels

Applications

• Telecommunications infrastructure timing
• Clock synchronization systems
• Rate conversion in digital networks

Procurement Notes

Verify the specific suffix 'LDF1' against the official Microchip datasheet to confirm the tape-and-reel packaging format and lead-free status. Ensure compatibility with the required 32-QFN footprint and check for any recent Product Change Notifications (PCN) regarding marking or packing changes before finalizing procurement orders.

Selection Notes

Select this component when a single-channel DPLL with a 2:4 conversion ratio is required for telecom applications. Confirm that the system design accommodates LVCMOS I/O standards and a 3.1V–3.5V power supply. Verify that the 100 MHz maximum frequency meets the target clock requirements and that the 32-VFQFN package fits the PCB layout constraints.

Part Context

This part belongs to the ZL30110 family of telecom rate converters. It is distinct from other variants like the ZL30110LDG1 primarily by its packaging type; the LDF1 suffix indicates a tape-and-reel configuration suitable for automated surface-mount assembly, whereas other suffixes may denote tray packaging.

Replacement Considerations

The ZL30110LDG1 is a functional equivalent within the same family, differing mainly in packaging (tray vs. tape-and-reel). Verify pinout and electrical specifications remain identical before substitution.
