ZL30634ALDG1Q09F

Overview

The ZL30634ALDG1Q09F is a system synchronizer from the ZL3063x family, featuring up to five independent clock channels with ten inputs and twenty outputs. It supports any-to-any frequency conversion for input frequencies ranging from 0.5 Hz to 1250 MHz and output frequencies from 0.5 Hz to 750 MHz. The device integrates up to eight DPLLs for timing compliance with ITU-T G.8262, G.813, and other standards. It operates on 1.8V and 3.3V core voltages and utilizes a 64-lead 9 mm x 9 mm VQFN package.

Feature Summary

• Up to five independent clock channels with any-to-any frequency conversion
• Supports up to 10 differential/CMOS inputs and 20 CMOS or 10 differential outputs
• Integrates up to 8 DPLLs with hitless reference switching and high-resolution holdover
• Includes MiToDSync and MiToDBasic interfaces for time-of-day synchronization

Applications

• Central system timing ICs for SyncE, SyncE+1588, routers, switches, and OTN
• Wireless base stations including 3G, W-CDMA, 4G/LTE, LTE-A, and 5G
• Remote Radio Units (RRU), Remote Access Networks (RAN), small cells, and wireless backhaul

Procurement Notes

Verify the specific ordering suffix Q09F against official Microchip documentation to confirm packaging details and environmental compliance status. Ensure that the selected variant matches the required pinout and configuration memory settings for the target application design.

Selection Notes

Select this component when designs require up to five independent synthesizers and eight DPLLs within a single chip. It is suitable for applications needing precise phase alignment, low jitter performance, and support for multiple telecom standards such as SyncE and IEEE 1588.

Part Context

This part belongs to the ZL30631-ZL30635 series of system synchronizers. The ZL30634 variant specifically provides four independent clock channels, distinguishing it from the ZL30635 which offers five channels. All variants share the same 64-lead VQFN package and general feature set.

Replacement Considerations

The ZL30635ALDG1Q09F is a compatible alternative within the same family, offering an additional clock channel while maintaining identical interface and package specifications.
