MC100LVEL32DR2

Counter Dividers Overview

The MC100LVEL32DR2G is a 3.3 V ECL ÷2 divider from onsemi, packaged in SOIC-8 NB with a tape and reel shipping format. It features a propagation delay of 510 ps and a typical maximum toggle frequency of 2.6 GHz. The device operates within a PECL mode range of VCC = 3.0 V to 3.8 V (VEE = 0 V) or an NECL mode range of VEE = -3.0 V to -3.8 V (VCC = 0 V). Power supply current ranges from 29 mA to 36 mA across the operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Asynchronous reset pin asserted on rising edge for system synchronization
• Internal reference voltage (VBB) available for single-ended input biasing
• Temperature compensation included in the 100 Series design
• ESD protection exceeding 4 kV Human Body Model and 200 V Machine Model

Counter Dividers Applications

• Clock signal division in high-speed digital systems
• Frequency synthesis circuits requiring precise timing
• Synchronization of multiple divider stages in complex logic arrays

Counter Dividers Procurement Notes

Verify the specific package suffix against the datasheet ordering information to ensure correct physical dimensions and shipping configuration. Confirm RoHS compliance status and Pb-Free marking requirements for your assembly process. Check for any recent Product Change Notices regarding manufacturing site transfers or material updates before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a 3.3 V low-voltage ECL interface is required for ÷2 frequency division. Ensure the application supports differential clock inputs or utilizes the internal VBB reference for single-ended configurations. Verify that the power supply architecture aligns with either PECL or NECL operating modes to meet the specified voltage ranges.

Counter Dividers Part Context

This part belongs to the MC100LVEL32 series of integrated dividers designed for low-voltage ECL applications. It is functionally identical to the EL32 but optimized for 3.3 V operation. The series provides high-speed performance with internal temperature compensation, making it suitable for demanding timing-critical environments where stable frequency division is essential.

Counter Dividers FAQ

How should the unused differential input be handled for single-ended operation?

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

What is the behavior of the internal flip-flop upon power-up?

Upon power-up, the internal flip-flop attains a random state. The asynchronous reset pin must be used to synchronize the device and establish a known initial state.
