Overview
The SY100EL33ZC is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology, housed in an 8-lead 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 and includes internal 75 kΩ input pull-down resistors. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated divide-by-four frequency divider functionality
- Supports differential, single-ended, or AC-coupled clock interfaces
- Includes asynchronous reset pin for system synchronization
Applications
- High-speed clock distribution networks
- Frequency division in telecommunications systems
- Digital signal processing hardware timing circuits
Procurement Notes
Verify the specific ordering suffix 'ZC' against official Microchip documentation, as datasheets typically list 'ZG' for lead-free SOIC packages. Confirm current availability status directly with authorized distributors, as component lifecycle stages may affect procurement options.
Selection Notes
Select this component when a precise divide-by-four ratio is required for high-frequency PECL or NECL signals. Ensure the design accommodates the specified 3.3V power supply constraints and utilizes the VBB reference output correctly for biasing if single-ended inputs are employed.
Part Context
This part belongs to the SY100EL series of high-speed ECL dividers from Microchip Technology. It provides a specialized solution for maintaining signal integrity at gigahertz frequencies while offering flexible interface options through its dedicated VBB pin and internal pull-down resistors.

FAQ
How should the VBB pin be utilized?
The VBB pin provides an internally generated reference voltage that can be used as an input bias for single-ended or AC-coupled interfaces. 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 EL33L devices within a system upon power-up.
