Overview
The SY10EL33LZI 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 a typical propagation delay of 640ps from clock input to output, with an asynchronous reset pin for system synchronization. It utilizes internal 75 kΩ input pull-down resistors and provides differential data outputs in an 8-pin SOIC package.
Feature Summary
- Integrated ÷4 frequency division capability
- Asynchronous reset functionality for flip-flop synchronization
- Internal 75 kΩ input pull-down resistors
- Supports differential, single-ended, or AC-coupled interfaces
Applications
- Clock distribution networks
- Frequency division circuits
- High-speed digital systems requiring precise timing
Procurement Notes
Verify the specific ordering suffix 'ZG' indicates a Pb-Free NiPdAu finish and industrial temperature rating (-40°C to +85°C). Confirm the package type matches the required 8-Lead SOIC footprint. Ensure compatibility with the intended power supply voltage range of 3.0V to 3.8V before finalizing procurement.
Selection Notes
Select this component when a high-speed ÷4 divider is required for PECL or NECL logic levels. The device is suitable for applications needing a maximum toggle frequency of 4.2 GHz. Consider the asynchronous reset feature if multiple dividers require synchronized initialization upon power-up.
Part Context
This part belongs to the Precision Edge SY10/100EL33/L series of high-speed ECL dividers. It is designed for demanding timing applications where low propagation delay and high bandwidth are critical. The device replaces older Micrel versions under the Microchip portfolio.

FAQ
How is the VBB pin utilized?
The VBB pin provides an internally-generated reference voltage that can be used as an input bias or switching reference. If used, it should 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 EL33L devices in a system, ensuring internal flip-flops attain a known state after power-up.
