MC100E210FN

Clock Buffers, Drivers Overview

The MC100E210FN is a dual differential ECL fanout buffer in a 28-lead PLCC package. It integrates two buffers: one with a 1:4 ratio and another with a 1:5 ratio, designed for clock distribution applications. The device supports PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = -4.2 V to -5.7 V). Key electrical specifications include a maximum toggle frequency of 700 MHz, typical output-to-output skew of 50 ps, and part-to-part skew of 200 ps. Power supply current is typically 55 mA at 25°C.

Clock Buffers, Drivers Feature Summary

• Dual differential fanout buffers (1:4 and 1:5) on a single chip
• Low skew performance with 50 ps typical output-to-output skew
• Compatible with low voltage ECL/PECL logic families
• Includes internal input pulldown resistors and temperature compensation

Clock Buffers, Drivers Applications

• Clock distribution networks requiring low skew
• High-speed digital systems utilizing ECL or PECL signaling
• Applications necessitating the simultaneous fanout of two distinct signals

Clock Buffers, Drivers Procurement Notes

Verify component status as the MC100E210 series is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the specific FN suffix corresponds to the PLCC-28 package variant required for the design. Check for RoHS compliance status if environmental regulations apply to the end product.

Clock Buffers, Drivers Selection Notes

Select this component when a single IC must drive two separate clock domains with minimal relative skew between them. The 1:4 and 1:5 split allows for asymmetric fanout requirements within the same footprint. Ensure the system operates within the specified voltage ranges for either PECL or NECL modes. Verify that the PCB layout can accommodate the 28-lead PLCC package dimensions.

Clock Buffers, Drivers Part Context

This device belongs to the MC100E family of high-speed ECL logic components manufactured by onsemi. The 'FN' suffix specifically denotes the 28-lead Plastic Leadless Chip Carrier (PLCC) package configuration. It serves as a specialized solution for reducing part-to-part skew compared to using multiple discrete buffers.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult application notes or contact the manufacturer for recommended alternatives due to the component's obsolete status.
