SY89853UMG

SY89853U Precision Low-Power Dual 2:1 LVPECL MUX with Internal Termination General Description The SY89853U features two, low jitter 2:1 differential multiplexers with 100K LVPECL (800mV) compatible outputs, capable of handling clocks up to 2.5GHz and data streams up to 2.5Gbps. The SY89853U differential inputs include Micrel’s unique, 3-input termination architecture that allows users to interface to any differential signal (AC- or DCCoupled) as small as 100mV without any level shifting or termination resistors networks in the signal path. The result is a clean, stub-free, low jitter interface solution. The differential 800mV LVPECL outputs have fast rise/fall times guaranteed to be less than 180ps. The SY89853U operates from a 2.5V ±5% or a 3.3V ±10% supply, and is guaranteed over the full industrial temperature range (–40°C to +85°C). For applications that require higher performance, consider the SY58026U. The SY89853U is part of Micrel's Precision ® Edge product family.
