MC100EL11DR2G

Clock Buffers, Drivers Overview

The MC100EL11DR2G is a differential 1:2 fanout buffer from the MC100EL series by onsemi, housed in an SOIC-8 package. It operates with PECL mode supply voltages of 4.2 V to 5.7 V or NECL mode supplies of -4.2 V to -5.7 V. The device features a typical propagation delay of 265 ps and within-device skew of 5 ps. It includes internal input pulldown resistors and clamping circuitry for stability under open input conditions. The component is Pb-Free, Halogen Free, and RoHS compliant.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer with 265 ps typical propagation delay
• Low within-device skew of 5 ps between outputs
• PECL operation range: VCC = 4.2 V to 5.7 V; NECL operation range: VEE = -4.2 V to -5.7 V
• Internal input pulldown resistors (75 kΩ) and clamping circuitry

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Differential signal buffering in telecommunications equipment
• Data acquisition systems requiring low jitter clock signals

Clock Buffers, Drivers Procurement Notes

Verify the current status of the MC100EL11DR2G as the datasheet indicates the base device may be discontinued for new designs. Confirm availability through authorized onsemi representatives. Ensure compliance with RoHS and lead-free requirements if applicable to the specific manufacturing batch.

Clock Buffers, Drivers Selection Notes

Select the MC100EL11DR2G when low skew and high-speed performance are required for ECL/PECL/NECL applications. Compare against the MC10EL11 for similar functionality but potentially different temperature compensation characteristics. Ensure the power supply voltage matches the specific PECL or NECL operating range defined in the datasheet.

Clock Buffers, Drivers Part Context

The MC100EL11 is part of the MC10EL/100EL family of ECL fanout buffers. It offers improved performance over the E111 device, particularly in within-device skew and propagation delay. The 100 Series specifically includes temperature compensation features not present in all variants.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes that the device is discontinued and recommends contacting onsemi representatives for information. No direct public substitute part numbers are listed in the provided documentation.
