MC10E211FNG

Clock Buffers, Drivers Overview

The MC10E211FNG is a low skew 1:6 fanout device designed for high-speed clock distribution. It features multiplexed inputs allowing selection between differential system clocks and single-ended scan/test clocks via the SEL pin. 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). It includes synchronous enabling/disabling to prevent runt pulses and provides individual output enables. Electrical specifications include a maximum toggle frequency of 700 MHz, typical power supply current of 160 mA at 25°C, and guaranteed part-to-part skew of 50 ps.

Clock Buffers, Drivers Feature Summary

• Multiplexed clock input with SEL pin for switching between differential CLK and single-ended SCLK
• Synchronous enable/disable control (CEN and ENx) prevents runt pulse generation during state transitions
• Internal VBB reference voltage output for single-ended input biasing or AC coupling rebiasing
• Guaranteed low skew specification with 50 ps part-to-part skew and < 1 ps RMS jitter

Clock Buffers, Drivers Applications

• High-speed clock distribution trees in backplane systems
• System diagnostics and self-test procedures requiring lower speed scan clocks
• Fault-tolerant designs utilizing individual card disabling capabilities

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'G' indicates a lead-free package compliant with RoHS standards. Confirm the PLCC-28 tube packaging quantity of 37 units per rail matches the procurement requirement. Ensure the specific revision level of the datasheet aligns with design documentation requirements.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:6 fanout with tight skew limits is required alongside multiplexed clock sources. Use the 10E series for standard operating ranges or the 100 series if temperature compensation is necessary. Ensure termination guidelines are followed to maintain specified skew performance due to fast edge rates.

Clock Buffers, Drivers Part Context

This device belongs to the ECLinPS family, characterized by high bandwidth output transistors that provide faster edge rates than standard ECL devices. It is often used in conjunction with the MC10E111 to create multi-level clock distribution networks, leveraging the E211's flexibility for first-level distribution.

Clock Buffers, Drivers Replacement Considerations

The MC100E211FNG serves as a direct functional replacement within the same package, offering temperature-compensated characteristics. Verify compatibility regarding internal pull-down resistor values and specific DC electrical parameters before substitution.
