Description
General part information
SY89847U Series
The SY89847U is a 2.5V, 1:5 LVDS fanout buffer with a 2:1 differential input multiplexer (MUX). A unique Fail-Safe Input (FSI) protection prevents metastable output conditions when the selected input clock fails to a DC voltage (voltage between the pins of the differential input drops significantly below 100mV).The differential input includes Micrel's unique, 3-pin internal termination architecture that can 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 LVDS compatible with very fast rise/fall times guaranteed to be less than 210ps.The SY89847U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89847U is part of Micrel's high-speed, Precision Edge® product line.
