MC100ES6254AC

Clock Buffers, Drivers Overview

The MC100ES6254AC is a bipolar monolithic differential 2x2 clock switch and fanout buffer utilizing SiGe technology. It supports LVPECL signals with frequencies from DC to 3GHz, characterized up to 2.7GHz. The device operates on a single 2.5V or 3.3V supply without negative rails. Key electrical parameters include a maximum device skew of 50 ps and part-to-part skew of 250 ps. Propagation delay ranges from 360 ps to 610 ps. It features synchronous output enable to prevent runt pulses and metastability. The component is housed in a standard 32-lead Pb-free LQFP package.

Clock Buffers, Drivers Procurement Notes

Verify the manufacturing source, as the datasheet indicates IDT ownership while the model prefix suggests Freescale/Renesas lineage. Confirm RoHS compliance status for the specific batch. Check for discontinuance notices, as the document references a last-time buy expiration date of December 7, 2013. Ensure the ordering suffix matches the required tape and reel or tray configuration.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring precise alignment of multiple differential clock signals. Ensure the design accommodates a single 2.5V or 3.3V positive supply. Verify that the PCB thermal management can maintain junction temperatures within the 0°C to +110°C range for specified AC/DC performance. Consider the 32-lead LQFP package dimensions for layout constraints.
