SY100EP11UKG-TR

Clock Buffers, Drivers Overview

The SY100EP11UKG-TR is a precision, high-speed 1:2 differential fanout buffer from the ECL Pro™ family. It supports 2.5V, 3.3V, and 5V power supplies for PECL, LVPECL, ECL, and LVECL operation. The device features guaranteed AC parameters including a maximum toggle frequency exceeding 3.0GHz, output-to-output skew under 20ps, and propagation delay under 300ps. It is housed in an 8-pin MSOP package with industrial temperature range (-40°C to +85°C) and lead-free NiPdAu finish.

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 the design accounts for the specific DC electrical characteristics at the intended VCC voltage (2.5V, 3.3V, or 5V).

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high-frequency operation (>3GHz) are critical. Compare against the SY10EP11U variant if commercial temperature range is sufficient. Ensure termination resistors match the selected VCC level (e.g., R1=130Ω/R2=82Ω for 3.3V/5V) to maintain signal integrity.

Clock Buffers, Drivers Part Context

This part belongs to the Micrel SY10/100EP11U series of differential fanout buffers. It serves as an upgrade to the EL11V, offering improved within-device skews and output transition times. The '100' prefix typically denotes the industrial temperature grade compared to the '10' commercial grade.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers include MC10EP11D/DT and MC10LVEP11D/DT from ON Semiconductor. Verify pinout and electrical specifications before substitution.

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 the internal clamping circuitry.

How does the device handle single-ended input operation?

Single-ended input CLK pin operation is limited to VCC ≥ 3.0V in PECL mode and VEE ≤ -3.0V in ECL/LVECL mode.

What is the recommended termination for a 3.3V system?

For a 3.3V system, use R1 = 130Ω and R2 = 82Ω for Thevenin termination, or Rb = 46Ω to 50Ω for Y-termination.
