SY58610U
3.2Gbps Precision, LVPECL 2:1 MUX with
Internal Termination and Fail Safe Input General Description
The SY58610U is a 2.5/3.3V, high-speed, fully
differential LVPECL 2:1 MUX capable of processing
clock signals up to 2.5GHz and data patterns up to
3.2Gbps. The SY58610U is optimized to provide a
buffered output of the selected input with less than
10pspp total jitter.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that interfaces to LVPECL,
LVDS or CML differential signals, (AC-or DC-coupled)
as small as 100mV (200mVPP) without any level-shifting
or termination resistor networks in the signal path. For
AC-coupled input interface applications, an integrated
reference voltage (VREF-AC) is provided to bias the VT pin.
The outputs are 800mV LVPECL, with extremely fast
rise/fall times guaranteed to be less than 130ps.
The SY58610U operates from a 2.5V В±5% supply or
3.3V В±10% supply and is guaranteed over the full
industrial temperature range (–40°C to +85°C). For
applications that require CML or LVDS outputs, consider
