GENERAL DESCRIPTION
The BCT4227 is a high bandwidth, fast
double-pole double-throw (DPDT) analog
switch. Its wide bandwidth and low bit-to-bit
skew allow it to pass high-speed differential
signals with good signal integrity. Each
switch is bidirectional and offers little or no
attenuation of the high-speed signals at the
outputs.
Industry-leading
advantages
include a propagation delay of less than
250ps, resulting from its low channel
resistance and low I/O capacitance. Its high
channel-to-channel
crosstalk
rejection
results in minimal noise interference.
APPLICATIONS
Cell
PDAs
Portable Instrumentation
Differential Signal Data Routings
USB 2.0 Signal Routing
Phones
