SY89473U
Precision LVPECL 2:1 Multiplexer with 1:2
Fanout and Internal Termination
General Description
The SY89473U is a 2.5V/3.3V precision, high-speed 2:1
differential MUX capable of processing clocks up to
2.5GHz and data up to 2.5Gbps.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that directly interfaces to
any differential signal (AC- or DC-coupled) as small as
100mV (200mV
PP
) 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 SY89473U operates from a 2.5V ±5% or 3.3V
±10% supply and is guaranteed over the full industrial
temperature range of –40°C to +85°C. The SY89473U is
part of Micrel’s high-speed, Precision Edge
product
line. For multiple-clock switchover solutions, please refer
to the SY89840–SY89843U family.
