MC100LVEL33DTR2

Counter Dividers Overview

The MC100LVEL33DTR2G is a 3.3 V ECL divide-by-4 divider integrated circuit manufactured by onsemi. It operates within a supply voltage range of 3.0 V to 3.8 V and supports both PECL and NECL modes. The device features a typical propagation delay of 630 ps and a maximum toggle frequency of 4.0 GHz. It includes an asynchronous reset pin, internal input pulldown resistors, and temperature compensation. The component is housed in an 8-TSSOP package with tape and reel shipping.

Counter Dividers Feature Summary

• Asynchronous reset functionality for system synchronization
• Internal input pulldown resistors simplify external circuit design
• Temperature compensated operation across the industrial range
• Integrated VBB reference voltage output for single-ended inputs

Counter Dividers Applications

• High-speed clock distribution networks
• Frequency division in data communication systems
• Synchronization circuits requiring precise timing alignment

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DTR2G' corresponds to the TSSOP-8 package and tape and reel quantity of 2500 units. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the part number matches the exact functional specification required for your design.

Counter Dividers Selection Notes

Select this component when a divide-by-4 function is required at frequencies up to 4.0 GHz. Consider the 8-TSSOP package if space constraints favor surface mount technology over SOIC. Evaluate power consumption against system thermal limits, as the device draws approximately 37 mA at 25°C.

Counter Dividers Part Context

This device belongs to the MC100LVEL series, which provides high-speed ECL logic functions optimized for 3.3 V operation. It serves as a modern replacement for legacy EL33 devices, offering improved performance metrics while maintaining functional compatibility with existing ECL-based system architectures.

Counter Dividers FAQ

How should the VBB pin be handled if single-ended inputs are used?

Connect the unused differential input to the VBB pin, which acts as a switching reference voltage. Decouple VBB and VCC via a 0.01 µF capacitor and limit current sourcing or sinking to 0.5 mA.

What is the behavior of the reset pin upon power-up?

Upon power-up, the internal flip-flops attain a random state. The asynchronous reset pin allows for the synchronization of multiple LVEL33 devices in a system by asserting a reset signal.
