MC100LVEL11DR2G

Clock Buffers, Drivers Overview

The MC100LVEL11DR2G is a differential 1:2 fanout buffer manufactured by onsemi, designed for high-speed clock distribution in ECL and PECL applications. It operates within a supply voltage range of 3 V to 3.8 V and supports maximum input frequencies up to 1 GHz. The device features a typical propagation delay of 405 ps and is housed in an 8-SOIC surface-mount package. It includes temperature compensation and open-input default states, ensuring signal integrity in demanding environments with operating temperatures from -40°C to +95°C.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer supporting ECL and PECL logic families
• Maximum operating frequency of 1 GHz with 405 ps typical propagation delay
• Temperature compensated design with open-input default state protection
• Available in RoHS-compliant 8-SOIC (3.90 mm wide) surface-mount package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring differential signaling
• PECL mode circuitry operating between 3 V and 3.8 V supply rails
• ECL-based digital systems requiring low jitter fanout buffering
• Industrial or commercial equipment operating within -40°C to +95°C ranges

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix DR2G to confirm the tape-and-reel packaging format and lead-free status. Confirm that the 8-SOIC package width matches the PCB footprint requirements. Check current availability against the standard factory lead time, as production cycles may vary. Ensure the 3 V to 3.8 V supply voltage range aligns with the target system power architecture.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:2 differential fanout ratio is required for ECL/PECL signals. Compare the 1 GHz maximum frequency and 405 ps delay against system timing budgets. Consider the MC100EP11 series if higher frequency performance up to 3 GHz or wider voltage tolerance up to 5.5 V is needed. Verify that the SOIC-8 package dimensions fit the assembly constraints.

Clock Buffers, Drivers Part Context

This part belongs to the MC100LVEL11 series of low-voltage ECL buffers. It shares functional equivalence with the MC10LVEP11 but is optimized for the 3 V to 3.8 V operating range. The device provides two complementary outputs driven by a single differential input, serving as a fundamental building block for clock tree structures in high-speed digital designs.

Clock Buffers, Drivers Replacement Considerations

The MC100EP11DR2G serves as a higher-performance alternative within the same family, offering 3 GHz operation and 5.5 V support. Both parts share identical pinouts and package types, facilitating direct substitution where electrical specifications exceed minimum requirements.
