ZL40253LDG1

Overview

The ZL40253LDG1 is a clock multiplier and jitter attenuator manufactured by Microchip Technology. It features three outputs capable of operating at any rate, with a maximum output frequency of 1.035 GHz and a maximum input frequency of 1.25 GHz. The device operates on 1.8 V or 3.3 V supplies, drawing 242 mA of working power current. It is housed in a QFN-32 package, supports surface-mount installation, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated EEPROM for configuration storage
• Supports any-rate clock multiplication and jitter attenuation
• Three independent output channels

Applications

• High-speed data communication systems requiring precise clock generation
• Network infrastructure equipment needing low-jitter clock distribution
• Telecommunications base stations utilizing programmable clock multipliers

Procurement Notes

Verify the specific suffix 'UB' if required, as the primary datasheet references ZL30253LDG1. Confirm moisture sensitivity level (MSL) handling requirements due to the QFN-32 package type. Ensure supply voltage compatibility with 1.8 V or 3.3 V rails before integration into the design.

Selection Notes

Select this component when a single-chip solution for clock multiplication and jitter cleaning is needed. The QFN-32 package offers a compact footprint for space-constrained designs. Verify that the 1.035 GHz maximum output frequency meets the target system's bandwidth requirements.

Part Context

This part belongs to the SmartBuffer family of clock products from Microchip. It serves as a specialized clock generator and multiplier, distinct from simple fanout buffers like the ZL40255 series. The device integrates PLL functionality with jitter attenuation capabilities.

Replacement Considerations

Check for direct pin-compatible alternatives within the ZL402xx series. Verify if the ZL30253 variant without the UB suffix meets electrical specifications. Cross-reference with other Microchip clock multipliers offering similar I/O counts and frequency ranges.
