MC10E411FN

Clock Buffers, Drivers Overview

The MC10E411FN is a low skew 1-to-9 differential driver designed for clock distribution. It features 1.2 V output swings, enabling AC coupling into RAMBus compatible loads. The device operates in PECL mode with VCC = 4.5 V to 5.5 V and NECL mode with VEE = −4.5 V to −5.5 V. Maximum toggle frequency is 700 MHz. Propagation delay ranges from 350 ps to 850 ps depending on input configuration. Part-to-part skew is 200 ps, while output-to-output skew is 50 ps. Power supply current is 65 mA typical at 25°C. It is housed in a PLCC-28 package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix (e.g., FN vs FNR2) against the required packaging format. Confirm RoHS compliance status by checking for the 'G' suffix if lead-free components are mandatory. Ensure the datasheet revision matches the design requirements. Check for moisture sensitivity level constraints during storage and handling.

Clock Buffers, Drivers Selection Notes

Select this component when RAMBus compatibility or larger voltage swings are required compared to standard ECL buffers. Note that temperature compensated outputs are not available due to the lower VOL. Unused output pairs must be left open to minimize power consumption and switching noise. Verify termination resistor values as standard -2.0 V termination is incompatible.

Clock Buffers, Drivers Part Context

The MC10E411 belongs to the 10E series of ECL logic devices. It shares functional similarities with the MC10E111 but provides enhanced output swing characteristics. The device utilizes a PLCC-28 package and includes an internal VBB pin for single-ended input reference or AC coupling rebiasing.
