SY89847U
Description
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 100m V). 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 100m V (200m VPP) without any level shifting or termination resistor networks in the signal path. The outputs are LVDS patible 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. All support documentation can be found on Micrel’s web site at: .micrel..
