MC100LVEL33DTR2G

Counter Dividers Overview

The MC100LVEL33DTR2G is a 3.3 V ECL ÷4 divider integrated circuit manufactured by onsemi, housed in an 8-TSSOP surface-mount package. It operates within a supply voltage range of 3.0 V to 3.8 V with VEE at 0 V (PECL mode) or VCC at 0 V with VEE between -3.0 V and -3.8 V (NECL mode). The device features asynchronous reset functionality and supports toggle frequencies up to 4.0 GHz. Key electrical parameters include a typical propagation delay of 630 ps and a power supply current of approximately 37 mA at 25°C.

Counter Dividers Feature Summary

• Provides ÷4 frequency division using dual differential clock inputs and outputs.
• Includes an internally generated VBB reference pin for single-ended input biasing or AC coupling rebiasing.
• Features asynchronous reset capability to synchronize multiple dividers upon system startup.
• Incorporates internal input pulldown resistors to maintain stable states when differential inputs are left open.

Counter Dividers Applications

• High-speed clock distribution networks requiring frequency division.
• Synchronization circuits for multi-chip systems utilizing ECL logic families.
• Data processing interfaces operating under PECL or NECL voltage standards.

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DTR2G' confirms the TSSOP-8 tape and reel packaging configuration. Ensure compatibility with the required 3.3 V ECL supply architecture. Confirm that the moisture sensitivity level for the TSSOP-8 package aligns with your board assembly reflow profile requirements. Validate that the asynchronous reset timing meets your system synchronization constraints.

Counter Dividers Selection Notes

Select this component when a dedicated ÷4 divider is required rather than cascading ÷2 stages. Consider the 8-TSSOP package if space constraints preclude the SOIC-8 variant. Evaluate the 4.0 GHz maximum toggle frequency against your system clock requirements. Verify that the internal VBB pin utility matches your input signal termination strategy.

Counter Dividers Part Context

This device belongs to the MC100LVEL series, which offers low-voltage ECL performance optimized for 3.3 V operation. It is functionally equivalent to the legacy EL33 part but utilizes modern manufacturing processes. The series is characterized by temperature compensation and high-speed switching capabilities suitable for demanding digital communication environments.

Counter Dividers Replacement Considerations

The MC100LVEL33DG serves as the tube-packaged alternative within the same functional family. Direct substitution requires verifying that the package outline dimensions and pinout assignments remain identical for your PCB layout.
