ZL30255LFF7

Overview

The ZL30255LFF7 is a dual-channel clock multiplier and jitter attenuator manufactured by Microchip Technology. It supports up to six outputs with a maximum frequency of 1.035 GHz and accepts inputs up to 1.25 GHz. The device operates on supply voltages between 1.71 V and 3.465 V, consuming 184 mA or 242 mA depending on configuration. It features low jitter performance of 7.5 ps and supports multiple output formats including CMOS, HCSL, HSTL, LVDS, LVPECL, and SSTL. Packaged in an LGA-64 form factor, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture supporting any-to-any clock multiplication and jitter attenuation
• Maximum output frequency of 1.035 GHz with input frequencies up to 1.25 GHz
• Integrated EEPROM for configuration storage
• Supports six outputs with selectable logic levels: CMOS, HCSL, HSTL, LVDS, LVPECL, SSTL

Applications

• High-speed data communication systems requiring precise clock generation
• Networking equipment utilizing SONET/SDH standards
• Servers and storage arrays needing low-jitter clock distribution

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel specifications. Confirm RoHS compliance status through official documentation before procurement. Check current production lifecycle status to ensure long-term availability. Validate that the LGA-64 package matches the target PCB footprint requirements.

Selection Notes

Select this component when dual independent channels are required for separate clock domains. Ensure the design accommodates the 1.71 V to 3.465 V supply voltage range. Verify that the required output count does not exceed six channels. Consider the LGA-64 thermal and mechanical constraints during layout.

Part Context

This part belongs to the ZL302xx series of clock generators from Microchip Technology. It shares architectural similarities with other devices in the family but is distinguished by its dual-channel capability and integrated EEPROM. The LFF7 suffix indicates the specific package and tape-and-reel packaging configuration.

Replacement Considerations

Direct substitutes include other ZL302xx series variants such as ZL30256LFG7, though pinouts and output counts may differ. Verify functional equivalence regarding jitter performance and supported output formats before substitution.
