ZL30410QCG1

Overview

The ZL30410QCG1 is a multi-service line card phase-locked loop (PLL) manufactured by Microchip Technology, housed in an 80-pin LQFP package. It generates multiple clock signals for SONET, SDH, and PDH equipment, including ST-BUS and GCI interfaces. The device operates on a 3.3 V power supply and supports input reference frequencies of 8 kHz, 1.544 MHz, 2.048 MHz, and 19.44 MHz. It provides outputs such as 1.544 MHz, 2.048 MHz, 155.52 MHz LVDS, and frame pulses. The component meets GR-253-CORE Stratum 3 and G.813 SEC timing requirements with holdover accuracy of 70x10^-12.

Feature Summary

• Generates clocks for OC-3, STM-1, DS3, E3, DS2, DS1, E1, 19.44 MHz, and ST-BUS interfaces
• Provides hit-less reference switching between primary and secondary sources
• Meets GR-253-CORE SONET Stratum 3 and G.813 SEC timing compliance
• Holdover accuracy of 70x10^-12 satisfies GR-1244 Stratum 3E requirements

Applications

• Line card synchronization for SDH, SONET, DS3, E3, J2, E1, and DS1 interfaces
• Timing card synchronization for SDH and PDH network elements
• Clock generation for ST-BUS and GCI timing backplanes

Procurement Notes

Verify the QCG1 suffix indicates Pb-free matte tin finish, bake status, and drypack packaging. Confirm the operating temperature range is -40°C to +85°C. Ensure the 80-pin LQFP package matches the design footprint. Check RoHS compliance documentation provided by the manufacturer.

Selection Notes

Select this component when designing hardware control systems requiring Stratum 3 or G.813 compliant timing. The ZL30410 requires an external 20 MHz master clock oscillator for holdover operations. Hardware pin selection determines filter characteristics and output configurations without software intervention.

Part Context

This part belongs to the ZL30410 series of multi-service line card PLLs originally developed by Zarlink Semiconductor. The ZL30410QCG1 variant specifically denotes the lead-free version packaged in trays with moisture barrier protection. It serves as a timing solution for telecommunications infrastructure supporting both synchronous digital hierarchy and optical carrier standards.

Replacement Considerations

The datasheet lists ZL30410QCC as the standard tray version. No other public substitute part numbers are documented.
