SY58611U
3.2Gbps Precision, LVDS 2:1 MUX with
Internal Termination and Fail Safe Input General Description
The SY58611U is a 2.5V, high-speed, fully differential
LVDS 2:1 MUX capable of processing clocks up to
2.5GHz and data up to 3.2Gbps. SY58611U is
optimized to provide a buffered output of the selected
input with less than 20ps of skew and less than 10pspp
total jitter. Patented MUX Isolation design reduces
crosstalk and provides superior signal integrity.
The differential inputs include Micrel’s unique, 3-pin
input termination architecture that interfaces to LVPECL,
LVDS or CML differential signals, (AC-or DC-coupled)
as small as 100mVPK (200mVpp) without any levelshifting 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 output is LVDS compatible, with rise/fall
times guaranteed to be less than 120ps.
The SY58611U operates from a 2.5V В±5% supply and is
guaranteed over the full industrial temperature range
(–40°C to +85°C). For applications that require CML or
LVPECL output, consider the SY58609U and
SY58610U, 2:1 MUX with 400mV and 800mV output …
