SY100EP32VZG

Overview

The SY100EP32VZG is a 5V/3.3V ECL ÷2 divider featuring differential clock inputs and an asynchronous reset function. It operates within a supply voltage range of 3.0V to 5.5V for PECL or -5.5V to -3.0V for NECL configurations. The device guarantees a maximum toggle frequency exceeding 4 GHz with propagation delays ranging from 250 ps to 440 ps across the operating temperature range of –40°C to +85°C. It utilizes an 8-lead MSOP package and includes an internal VBB reference voltage output for input biasing.

Feature Summary

• Integrated divide-by-two functionality with differential clock inputs
• Asynchronous reset capability for synchronous system synchronization
• Internal VBB reference voltage generation for single-ended input biasing
• Temperature-compensated circuitry ensuring consistent performance

Applications

• High-speed clock distribution networks
• Frequency division in data center solutions
• Synchronization circuits requiring precise timing control
• ECL-based logic systems requiring low jitter performance

Procurement Notes

Verify the specific ordering suffix 'ZG' against official Microchip documentation to confirm the package type, lead finish, and temperature grade. Ensure compatibility with existing PCB footprints for the 8-lead MSOP configuration. Confirm that the selected variant meets the required environmental specifications for the intended application environment.

Selection Notes

Select this component when a high-frequency divide-by-two operation is required with differential inputs. Consider the 4 GHz maximum frequency and sub-nanosecond propagation delay characteristics. Evaluate the power supply requirements for either 3.3V or 5V PECL/NECL modes. Assess the need for an asynchronous reset feature to manage state initialization in complex digital systems.
