Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'KG' corresponds to the Pb-free package with NiPdAu finish and industrial temperature range as specified in the datasheet. Confirm the 'TR' suffix indicates tape and reel packaging. Ensure compatibility with the required logic family voltage levels before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high-frequency operation are critical. The device accommodates single-ended or differential inputs. For PECL mode, VEE must be connected to GND. Consider termination resistor values based on the specific system voltage (e.g., R1=130Ω, R2=82Ω for 3.3V systems) to ensure signal integrity.

Clock Buffers, Drivers Part Context

This part belongs to the SY10/100EP11U series, which includes variants like SY10EP11U and SY100EP11U. The SY10EP11UKG-TR specifically denotes the industrial temperature range version in an 8-pin MSOP package with Pb-free plating. It serves as a replacement for older devices like the EL11V with improved AC performance.

Clock Buffers, Drivers Replacement Considerations

Cross-reference table lists MC10EP11D/DT and MC10LVEP11D/DT as equivalents. Verify pinout and electrical specifications match before substitution. Note that the original manufacturer was Micrel, now part of Microchip Technology.

Clock Buffers, Drivers FAQ

What happens if the differential inputs are left open?

If the inputs are left open, the Q outputs will go LOW due to internal clamping circuitry designed to maintain stability.

How should the VEE pin be connected for PECL operation?

For PECL operation, the VEE pin should be connected to GND.

What is the maximum toggle frequency guaranteed for this device?

The maximum toggle frequency (fMAX) is guaranteed to be greater than 3.0GHz across the operating temperature range.
