Manufacturer Part Number
sy56017r
Description
Low Voltage 1.2v/1.8v/2.5v Cml 2 1 Mux 6.4gbps With Equalization
Manufacturer
Micrel Semiconductor
Datasheet
General Description
The SY56017R is a fully differential, low voltage
1.2V/1.8V/2.5V CML 2:1 MUX with input equalization.
The SY56017R can process clock signals as fast as 4.5
GHz or data patterns up to 6.4Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to CML differential
signals, without any level-shifting or termination resistor
networks in the signal path. The differential input can also
accept AC-coupled LVPECL and LVDS signals. Input
voltages as small as 200mV (400mV
before the 9”, 18” or 27” FR4 transmission line. For AC-
coupled input interface applications, an internal voltage
reference is provided to bias the V
CML, with extremely fast rise/fall times guaranteed to be
less than 80ps.
The SY56017R 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
(–40°C to +85°C). The SY56017R is part of Micrel’s high-
speed, Precision Edge
Data sheets and support documentation can be found on
