ZL30631LDG1S

Overview

The ZL30631LDG1S is a system synchronizer featuring up to five independent clock channels, ten inputs, and twenty outputs. It supports any-to-any frequency conversion with input frequencies from 0.5 Hz to 1250 MHz and output frequencies from 0.5 Hz to 750 MHz. The device includes up to eight DPLLs for timing compliance with ITU-T G.8262 and G.813 standards. Output jitter is typically 100 fsRMS at 156.25 MHz (12 kHz to 20 MHz bandwidth). Core power consumption is less than 0.9W. It operates from a single local oscillator between 9.72 MHz and 400 MHz and utilizes a 64-lead 9 mm x 9 mm VQFN package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout, package type, and configuration options. Ensure compatibility with required SPI or I2C interfaces and voltage levels (1.8V and 3.3V core VDD) during component sourcing.

Selection Notes

Select this model when requiring up to five independent clock channels with high-density I/O capabilities. Verify that the application requires support for up to 10 inputs and 20 outputs. Confirm that the operating temperature range and power consumption constraints align with the device specifications.

Part Context

This part belongs to the ZL3063x family of system synchronizers, which includes models ZL30631 through ZL30635. These devices are designed for carrier-grade systems requiring precise timing synchronization across multiple clock domains.

Replacement Considerations

Consult the official product brief for confirmed substitute part numbers within the ZL3063x family. Verify channel count and I/O configurations before substitution.
