SY56572XR
Low Voltage 1.2V/1.8V/2.5V CML
4:1 MUX with 1:2 FANOUT
6.4Gbps with EQUALIZATION
.
General Description
The SY56572XR is a fully differential, low voltage
1.2V/1.8V/2.5V CML 4:1 Mux, with input equalization,
and integrated 1:2 Fanout Buffer. The SY56572XR can
process clock signals as fast as 4.5GHz or data patterns
up to 6.4Gbps.
The differential input includes Micrelâs unique 3-pin input
termination architecture that interfaces to DC-coupled
2.5V/3.3V LVPECL, 1.2V/1.8V/2.5V CML or LVDS
differential signals. For AC-coupled input applications,
an internal voltage reference is provided for input bias.
Input voltages as small as 200mV (400mVpp) are applied
before the 9, 18 or 27-inch FR4 transmission line.
The SY56572XR operates from a 2.5V ±5% core supply
and a 1.2V, 1.8V or 2.5V ±5% output supply and is
guaranteed over the full industrial temperature range
(â40°C to +85°C). The SY56572XR is part of Micrelâs
high-speed, Precision Edge® product line.
