SY100EL32VZI

Overview

The SY100EL32VZI is a Precision Edge integrated ÷2 divider manufactured by Microchip Technology. It supports both 3.3V and 5V power supply options, accommodating PECL and NECL logic families. The device features a typical propagation delay of 510 ps and a maximum toggle frequency of 3.0 GHz. It operates within an ambient temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package.

Feature Summary

• Supports differential, single-ended, or AC-coupled clock input interfaces via dedicated CLK and /CLK pins.
• Includes an asynchronous reset pin that synchronizes internal flip-flops upon assertion on the rising edge.
• Provides a VBB reference voltage output for biasing applications, requiring external bypassing to ground.

Applications

• High-speed clock signal division
• Frequency synthesis systems
• Data communication timing circuits

Procurement Notes

Verify the specific ordering suffix 'ZG' against the datasheet to confirm the package type (8-Lead SOIC) and lead finish (Pb-free NiPdAu). Ensure the required temperature grade matches the 'G' designation (-40°C to +85°C). Confirm whether tape-and-reel or tube packaging is needed for the manufacturing process.

Selection Notes

Select this component when a high-bandwidth ECL divider with low propagation delay is required. It is suitable for designs needing flexible input coupling methods and precise synchronization capabilities through its asynchronous reset feature. Ensure the power supply configuration aligns with either PECL or NECL standards.

Part Context

This part belongs to the SY10/100EL series of Precision Edge dividers from Microchip Technology. It is designed for high-performance clock distribution networks where signal integrity and speed are critical parameters for system operation.

Replacement Considerations

Direct substitutes include SY100EL32VZG and SY100EL32VZC. Verify compatibility regarding package dimensions and electrical characteristics before implementation.

FAQ

How does the RESET pin function?

The RESET pin is asynchronous and is asserted on the rising edge, allowing for the synchronization of multiple EL32Vs in a system.

What is the purpose of the VBB pin?

The VBB pin provides an output reference voltage. If used, it should be bypassed to ground with a 0.01 µF capacitor.
