ZL30702LDG6

Overview

The ZL30702LDG6 is a clock synthesizer IC designed for Ethernet applications, manufactured by Microchip Technology. It features four outputs and utilizes a 100-aQFN (10x10) package with exposed pad. The device supports differential inputs and outputs, accepting CML, HCSL, LVDS, or LVPECL input signals and providing CML or LVCMOS output levels. It incorporates a Phase-Locked Loop (PLL) with a 5:8 input-to-output ratio. The component operates within a temperature range of -40°C to +85°C and is classified as obsolete.

Feature Summary

• Four-output clock synthesizer optimized for Ethernet timing
• Supports multiple input formats including CML, HCSL, LVDS, and LVPECL
• Provides flexible output configurations in CML or LVCMOS
• Integrated PLL with 5:8 frequency ratio

Applications

• Ethernet network infrastructure equipment
• Clock distribution systems requiring low jitter performance
• Telecommunications base stations

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Microchip Technology. Verification of availability should focus on the recommended replacement part number ZL30732LDG1. Users must confirm current stock status through authorized distributors, as direct procurement from the manufacturer is not possible. Compliance with RoHS3 and REACH standards is documented.

Selection Notes

Designers should evaluate the ZL30732LDG1 as the primary alternative due to the discontinuation of the ZL30702LDG6. Selection criteria must account for potential differences in pinout compatibility and electrical specifications between the legacy and replacement devices. Verify that the target application requirements for input/output voltage levels and operating temperature ranges are met by the substitute component.

Part Context

The ZL30702 belongs to the ZL3070y family of clock synthesizers. This series is engineered for high-performance networking applications. The specific LDG6 suffix indicates the 100-aQFN package variant. The product has been subject to Product Change Notifications regarding marking changes and assembly sources, reflecting its mature lifecycle stage prior to obsolescence.

Replacement Considerations

Microchip recommends the ZL30732LDG1 as the functional replacement. Engineers must perform a thorough design-in review to ensure mechanical and electrical compatibility before transitioning production.
