Overview
The SY100EL33LZI-TR is a 3.3V integrated ÷4 divider manufactured by Microchip Technology in an 8-pin SOIC package. It operates with a power 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 rise/fall times ranging from 100ps to 350ps. It includes internal 75 kΩ input pull-down resistors and provides differential outputs.
Feature Summary
- Integrated frequency division functionality with asynchronous reset capability for system synchronization
- Supports differential, single-ended, or AC-coupled clock interfaces via dedicated inputs and VBB bias pin
- High bandwidth output transitions ensuring signal integrity at elevated operating frequencies
Applications
- Clock distribution networks requiring precise frequency division
- Synchronization of multiple divider stages within complex digital systems
- High-speed data acquisition systems utilizing differential signaling
Procurement Notes
Verify the specific ordering suffix 'ZG-TR' against official Microchip documentation to confirm tape and reel packaging and lead-free specifications. Ensure the procurement channel sources genuine components directly from authorized distributors to maintain reliability standards and avoid counterfeit risks.
Selection Notes
Select this component when a low skew, high-speed ÷4 divider is required for PECL or NECL logic families. Confirm that the application environment remains within the specified -40°C to +85°C temperature range and that the 3.3V power supply constraints align with the system design requirements.
Part Context
This part belongs to the SY100EL series of high-speed ECL dividers designed for demanding timing applications. It represents a transition from legacy Micrel designs now managed under Microchip Technology's portfolio, maintaining compatibility with established Precision Edge architecture while offering updated manufacturing processes.

FAQ
What is the function of the VBB pin on the SY100EL33L?
The VBB pin serves as an output reference voltage and can be used as an input bias for the EL33L. It should be bypassed to ground with a 0.01µF capacitor if utilized.
How does the Reset pin operate?
The Reset pin is asynchronous and is asserted on the rising edge. It allows for the synchronization of multiple EL33L devices within a system upon power-up.
