Product Overview
The SY89841UMG is a 2:1 precision LVDS Runt Pulse Eliminator Multiplexer optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89841U 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 Micrel's 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 outputs are 350mV, LVDS with fast rise/fall times guaranteed to be less than 150ps. The SY89841U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range of -40 to 85°C.
