ZL30406QGG1

Overview

The ZL30406QGG1 is a SONET/SDH clock multiplier integrated circuit manufactured by Microchip Technology. It operates with a maximum frequency of 155.52 MHz and features a 2:1 input-to-output ratio. The device utilizes a Phase-Locked Loop (PLL) architecture and is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 10x10 mm. It supports CMOS inputs and outputs, functioning within a supply voltage range of 3V to 3.6V and an operating temperature range of -40°C to +85°C.

Feature Summary

• SONET/SDH compliant Stratum clock generation
• Maximum output frequency of 155.52 MHz
• 64-pin TQFP surface-mount package
• Single circuit configuration with PLL

Applications

• SONET network synchronization
• SDH transmission systems
• Stratum timing applications

Part Context

This component belongs to the ZL30407 family of specialized clock generators designed for telecommunications infrastructure. While the ZL30407 series typically offers higher pin counts or different I/O configurations, the ZL30406 variant provides a compact solution for specific SONET/SDH frequency multiplication requirements within the same operational envelope.

Replacement Considerations

Public documentation indicates that the ZL30406QGG1 has been discontinued. Potential replacement candidates within the Microchip portfolio include the ZL30407 series or other SONET/SDH clock multipliers, though specific cross-references require verification against current availability and exact pinout compatibility.
