SY10EL33LZC-TR

Overview

The SY10EL33LZC-TR is a 3.3V ECL ÷4 divider integrated circuit manufactured by Microchip Technology. It operates within a power supply 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 data outputs (Q, /Q). The component is housed in an 8-pin SOIC package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports differential, single-ended, or AC-coupled clock interfaces via dedicated inputs and VBB reference voltage.
• Includes an asynchronous Reset pin asserted on the rising edge for system synchronization.
• Features internal 75 kΩ input pull-down resistors to stabilize input states.

Applications

• High-speed clock frequency division
• Differential clock signal distribution
• Synchronization of multiple divider circuits in timing systems

Procurement Notes

Verify that the ordering suffix matches the required packaging format. Confirm the specific package variant aligns with design constraints. Ensure the component meets all electrical specifications for the intended operating environment. Cross-reference the datasheet revision to confirm compatibility with current design requirements.

Selection Notes

Select this component when a high-frequency ÷4 divider is required for PECL or NECL applications. Consider the 4.2 GHz toggle frequency limit and 640ps propagation delay for timing budget calculations. Verify that the 8-pin SOIC package fits the board layout. Ensure the power supply voltage remains within the 3.0V to 3.8V range for proper operation.

Part Context

FAQ

How should the VBB pin be handled if used?

If used as an input bias, the VBB output must be bypassed to ground with a 0.01µF capacitor. It has limited current sink and source capability.

What is the function of the Reset pin?

The Reset pin is asynchronous and is asserted on the rising edge. It allows for the synchronization of multiple EL33L devices in a system upon power-up.
