DESCRIPTION
■ Selects 1 of 4 differential inputs
■ Provides two copies of the selected input
■ Guaranteed AC performance over temperature and
voltage:
DC-to- > 10.7Gbps data rate throughput
< 350ps IN-to-Out tpd
< 60ps tr /tf times
■ Ultra low-jitter design:
< 10psPP total jitter (clock)
< 1psRMS random jitter
< 10psPP deterministic jitter
< 0.7psRMS crosstalk-induced jitter
■ Unique patended input design minimizes crosstalk
■ Accepts an input signal as low as 100mV
■ Unique patended input termination and V
T pin
accepts DC- and AC-coupled inputs (CML, LVPECL,
LVDS)
■ Internal 50 output source termination
■ 400mV CML output swing (R
L = 50)
■ Power supply 2.5V ±5% or 3.3V ±10%
■ –40°C to +85°C temperature range
■ Available in 32-pin (5mm ×
×
× 5mm) MLF package

The SY58028U is a 2.5V/3.3V precision, high-speed, 4:1
differential CML multiplexer capable of handling clocks up
to 7GHz and data streams up to 10.7Gbps. In addition, a
1:2 fanout buffer provides two copies of the selected inputs.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows customers to interface to
any differential signal (AC- or DC-coupled) as small as 100mV
without any level shifting or termination resistor networks in
the signal path. The result is a clean, stub-free, low-jitter
interface solution. The outputs are 50 source terminated
CML, with extremely fast rise/fall times guaranteed to be less
than 60ps.
The SY58028U operates from a 2.5V ±5% supply or a
3.3V ±10% supply and is guaranteed over the full industrial
temperature range of –40°C to +85°C. For applications that
require LVPECL outputs, consider the SY58029U or
SY58030U Multiplexers. The SY58028U is part of Micrel’s
high-speed, Precision Edge product line.
