MC10EP11DTR2G

Clock Buffers, Drivers Overview

The MC10EP11DTR2G is a differential 1:2 fanout buffer from the onsemi MC10EP11 series, designed for high-speed clock distribution. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from −3.0 V to −5.5 V (VCC = 0 V). The device features a typical propagation delay of 220 ps and supports maximum clock frequencies exceeding 3 GHz. It includes safety clamps on inputs, open input default states, and RoHS compliance. Packaged in an 8-lead TSSOP with a tape and reel shipping configuration.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer with typical propagation delay of 220 ps
• Maximum clock frequency greater than 3 GHz
• PECL operation range: VCC = 3.0 V to 5.5 V with VEE = 0 V
• NECL operation range: VCC = 0 V with VEE = −3.0 V to −5.5 V

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Differential signal buffering in communication systems
• Fanout buffering for ECL/PECL logic circuits

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'DTR2G' corresponds to the TSSOP-8 package and tape & reel quantity of 2500 units as listed in the official ordering information table. Confirm that the 'G' suffix indicates Pb-Free, Halogen Free, and RoHS compliant status. Check for any discontinuation notices or recommended new design alternatives provided by the manufacturer.

Clock Buffers, Drivers Selection Notes

Select this component when a differential 1:2 fanout buffer with AC performance faster than the LVEL11 equivalent is required. Ensure the power supply configuration matches either PECL (positive VCC) or NECL (negative VEE) requirements. Verify that the TSSOP-8 package fits the PCB layout constraints and that the thermal resistance characteristics are suitable for the operating environment.

Clock Buffers, Drivers Part Context

The MC10EP11DTR2G belongs to the MC10EP11 family, which is pin and functionally equivalent to the LVEL11 device but offers superior AC performance. The 'MC10' prefix denotes the standard voltage range, while 'DT' specifies the TSSOP-8 package and 'R2' indicates the tape and reel packaging format. This part is distinct from the MC100EP11 series, which includes temperature compensation.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes that some devices in this family are discontinued. For the MC10EP11DTG (TSSOP-8 tube), the document explicitly lists it as discontinued. No direct public substitute part numbers are provided in the source material; consult the manufacturer for current alternatives.
