ZL30402QCG1

Overview

The ZL30402QCG1 is a SONET/SDH Stratum clock generator manufactured by Microchip Technology. It operates at a maximum frequency of 155.52 MHz with a single circuit configuration. The device features a 2:12 input-to-output ratio and utilizes an internal Phase-Locked Loop (PLL). It supports CMOS and LVDS output types, powered by a supply voltage ranging from 3V to 3.6V. The component is housed in an 80-LQFP package measuring 14x14 mm and is designed for surface mount installation. It functions within a temperature range of -40°C to 85°C.

Procurement Notes

The ZL30402QCG1 is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status confirmation. No new production units are expected.

Selection Notes

Select this component only if SONET/SDH Stratum compliance at 155.52 MHz is required. Ensure the design accommodates the 80-LQFP footprint and 3V-3.6V power supply. Verify that CMOS or LVDS outputs meet interface requirements, as differential inputs are not supported.

Part Context

This part belongs to the ZL30402 family of programmable clock generators. It is specifically optimized for telecommunications timing applications requiring high stability and low jitter performance consistent with SONET/SDH standards.

Replacement Considerations

As the part is discontinued, verify functional equivalents within the same Microchip ZL30xxx series or consult distributor cross-reference tools for compatible SONET/SDH clock ICs with matching pinouts and electrical specifications.
