ZL30633LDG1

Overview

The ZL30633LDG1 is a system synchronizer featuring up to five independent clock channels, ten inputs, and twenty outputs. It accepts input frequencies from 0.5 Hz to 1250 MHz and generates output clocks 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 Telcordia standards. Output jitter is typically 100 fsRMS at 156.25 MHz. It operates on 1.8V and 3.3V core supplies within a -40°C to +85°C temperature range in a 64-lead VQFN package.

Feature Summary

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

Applications

• Central system timing for SyncE and SyncE+1588 networks
• Wireless base stations including 3G, LTE, and 5G architectures
• Remote Radio Units (RRU) and wireless backhaul systems
• Carrier-grade routers, switches, and OTN equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product brief to confirm pinout and feature availability. Confirm that the component meets RoHS requirements and check for moisture sensitivity level details prior to assembly planning.

Selection Notes

Select this model when requiring up to five synthesizers and eight DPLLs within a single package. Ensure the design supports the required input/output voltage levels of 1.8V to 3.3V. Verify that the application utilizes SPI or I2C interfaces for configuration and monitoring.

Part Context

This part belongs to the ZL30631 through ZL30635 family of system synchronizers. The ZL30633 variant specifically provides five clock channels and eight DPLLs. Other family members offer varying counts of channels and DPLLs to suit different complexity requirements.

Replacement Considerations

Consult the official product brief for direct substitutes within the ZL3063x series. Verify channel counts and DPLL numbers match the original design requirements before considering alternative models.
