SY100EL33LZG

Overview

The SY100EL33LZG is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology. 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 differential clock inputs, an asynchronous reset pin, and a VBB reference voltage output. Electrical characteristics include a typical propagation delay of 640ps from CLK to Q and 460ps from RESET to Q. It is housed in an 8-lead SOIC package with an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Supports differential, single-ended, or AC-coupled clock input interfaces
• Includes internal 75 kΩ input pull-down resistors for signal stability
• Provides an asynchronous Reset pin for system synchronization
• Features high bandwidth output transitions for fast signal processing

Applications

• High-speed clock distribution networks
• Frequency division in digital communication systems
• Synchronization of multiple divider circuits in complex logic designs

Procurement Notes

Verify the specific ordering suffix (e.g., ZG for tube packaging) against official Microchip documentation to ensure correct physical form factor. Confirm that the required temperature range (-40°C to +85°C) aligns with your environmental specifications. Check for any recent product change notifications (PCN) regarding manufacturing updates or material composition changes before finalizing procurement plans.

Selection Notes

Select this component when a precise divide-by-4 function is required for PECL or NECL signals at frequencies approaching 4.2 GHz. Ensure the design accommodates the 3.3V power supply requirements and provides adequate bypassing for the VBB output pin. Consider the 8-pin SOIC footprint constraints during PCB layout planning.

Part Context

This part belongs to the SY10/100EL33/L series of 3.3V ECL dividers. It serves as a successor to legacy Micrel devices like the SY10EL33, maintaining compatibility while offering updated manufacturing standards. The 'Z' suffix indicates an 8-lead SOIC package, and 'G' denotes lead-free NiPdAu plating with industrial temperature ratings.

Replacement Considerations

SY100EL33LZG-TR is the tape-and-reel variant of the same functional device.
