ZL40814/DCE

Overview

The ZL40814/DCE is a fixed modulus frequency divider manufactured by Zarlink Semiconductor. It operates as a divide-by-16 counter with a single element and four-bit architecture. The device supports an input voltage range of 4.75 V to 5.25 V and functions within an operating temperature range of -40°C to +85°C. Packaged in an 8-SOIC (3.90mm width) with an exposed pad, it utilizes surface mount technology for integration into electronic circuits.

Feature Summary

• Fixed modulus division functionality providing stable frequency reduction
• Surface mount packaging design for automated assembly processes
• Industrial temperature rating for reliable operation in varied environments

Applications

• Frequency synthesis systems requiring precise division ratios
• Clock distribution networks in telecommunications equipment
• RF signal processing circuits in test and measurement instruments

Procurement Notes

Verify the specific suffix DCE confirms the 8-SOIC-EP package and industrial temperature grade. Confirm RoHS compliance status matches current regulatory requirements for your region. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and lot traceability before finalizing procurement orders.

Selection Notes

Select this component when a fixed divide-by-16 ratio is required without programmable logic complexity. Consider the exposed pad thermal performance for power dissipation management. Evaluate the 5V supply compatibility against existing system voltage rails. Verify interface requirements match the fixed modulus nature rather than variable dividers.

Part Context

This part belongs to the ZL4081x series of fixed modulus dividers from Zarlink. These components are designed for high-frequency applications up to 13.5GHz. The series offers various division ratios, with the ZL40814 specifically configured for divide-by-16 operations. They serve as fundamental building blocks in RF front-end architectures.

Replacement Considerations

Check datasheets for equivalent parts offering identical divide-by-16 functionality and compatible pinouts. Verify that alternative packages maintain similar thermal characteristics and electrical specifications. Ensure substitute components meet the same operating temperature and voltage range requirements.
