ZL30255LFG7

Overview

The ZL30255LFG7 is a dual-channel clock multiplier and jitter attenuator manufactured by Microchip Technology. It supports any-to-any clock multiplication with integrated EEPROM for configuration storage. The device features six outputs capable of generating frequencies up to 1.035 GHz, derived from an input frequency range extending to 1.25 GHz. It operates within a supply voltage range of 1.71 V to 3.465 V and is housed in an LGA-64 package. The component supports multiple output logic standards including CMOS, HCSL, HSTL, LVDS, LVPECL, and SSTL, ensuring compatibility with diverse system requirements.

Feature Summary

• Dual-channel architecture supporting independent clock generation paths
• Integrated EEPROM for non-volatile configuration retention
• Six configurable outputs with support for multiple voltage standards
• Maximum output frequency of 1.035 GHz with jitter specification of 7.5 ps

Applications

• High-speed data communication systems requiring precise clock synchronization
• Network infrastructure equipment utilizing SONET/SDH or Ethernet protocols
• Server and storage subsystems demanding low-jitter clock distribution

Procurement Notes

Verify the specific suffix 'LFG7' against the manufacturer's current datasheet to confirm pinout and electrical characteristics, as suffixes often denote package type or temperature grade. Confirm RoHS compliance status through official documentation before integration. Ensure ESD handling procedures are followed due to the LGA-64 surface mount packaging. Cross-reference the Mouser part number 494-ZL30255LFF7 if alternative sourcing is considered, noting potential differences in reel quantities.

Selection Notes

Select this component when a dual-channel solution with high output fan-out (six outputs) is required. The 1.25 GHz maximum input frequency allows flexibility for various reference clocks. Consider the 7.5 ps jitter performance for sensitive analog or high-speed digital interfaces. The LGA-64 package requires appropriate PCB layout considerations for thermal dissipation and signal integrity compared to smaller QFN packages found in other series members.

Part Context

This part belongs to the ZL302xx family of clock multipliers and jitter attenuators. It shares architectural similarities with the ZL30252LDG1 and ZL30256LFG7 but differs in output count and package style. While the ZL30252 offers three outputs in a QFN-32 package, and the ZL30256 provides eighteen outputs in an LGA-80, the ZL30255LFG7 occupies a middle ground with six outputs in an LGA-64 footprint, balancing channel density with board space constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate the ZL30252LDG1 for lower output count requirements or the ZL30256LFG7 for higher density needs, verifying electrical compatibility and pin mapping independently.
