SY89840U Precision LVPECL Runt Pulse Eliminator 2:1

The SY89840U is a low jitter PECL, 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89840U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or runt pulses during switchover. In addition, a unique Fail-Safe Input protection prevents metastable conditions when the selected input Clock fails to a DC voltage (voltage between the pins of the differential input drops below 100mV). The differential input includes Micrels unique, 3-pin input termination architecture that allows customers to Interface to any differential signal (AC or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The output is 800mV, 100K compatible LVPECL with fast rise/fall times guaranteed to be less than 190ps. The SY89840U operates from a 2.5V 5% or 3.3V 10% supply and is guaranteed over the full industrial temperature range of 40C to +85C. The SY89840U is part of Micrels high-speed, Precision Edge product line. By Micrel Semiconductor
