SY10EP11UKG

Clock Buffers, Drivers Overview

The SY10EP11UKG 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 guarantees AC performance with a maximum toggle frequency exceeding 3.0GHz, output-to-output skew under 20ps, and propagation delay under 300ps. It features internal clamping circuitry on differential inputs to maintain stability when left open. The component is housed in an 8-pin MSOP package and operates within a temperature range of –40°C to +85°C.

Clock Buffers, Drivers FAQ

What happens if the differential inputs are left open?

The internal clamping circuitry ensures that if the D and /D inputs are left floating, the Q outputs will default to a LOW state.

What is the maximum toggle frequency?

The device guarantees a maximum toggle frequency (fMAX) greater than 3.0GHz across the operating temperature range.

How does the device handle input common mode range?

The input common mode range (VIHCMR) is specified from 1.2V to VCC for PECL/LVPECL modes, referenced to the most positive side of the differential input signal.
