SY100EL33LZC

Overview

The SY100EL33LZC is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology, housed in an 8-pin SOIC package. It operates within a supply voltage range of 3.0V to 3.8V and supports toggle frequencies up to 4.2 GHz. The device features a typical propagation delay of 640ps from clock input to output and 460ps from reset to output. It includes internal 75 kΩ input pull-down resistors and provides differential outputs (Q, /Q). The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

Applications

• High-speed clock signal distribution networks
• Frequency division circuits in telecommunications infrastructure
• Synchronization logic for multi-chip digital systems
• Differential buffer interfaces requiring precise timing alignment

Procurement Notes

Verify the specific ordering suffix 'ZC' against official Microchip documentation, as standard listings typically utilize 'ZG'. Confirm current availability status directly with authorized distributors, as this part number may be subject to discontinuation or limited stock constraints. Ensure compatibility with existing PCB land patterns for the 8-pin SOIC footprint before finalizing procurement orders.

Selection Notes

Select this component when a low-power 3.3V ECL divider is required for frequencies approaching 4.2 GHz. It is suitable for designs needing flexible input coupling options and internal bias generation. Consider the 8-pin SOIC package size for space-constrained layouts. Evaluate thermal requirements to ensure operation remains within the specified -40°C to +85°C industrial range during continuous duty cycles.

FAQ

How should the VBB pin be utilized?

The VBB pin provides an internally generated reference voltage intended for use as an input bias. If used, it must be bypassed to ground with a 0.01µF capacitor.

What is the function of the Reset pin?

The Reset pin is asynchronous and asserted on the rising edge. It allows for the synchronization of multiple dividers in a system, ensuring internal flip-flops attain a known state after power-up.
