DS26900
JTAG Multiplexer/Switch
General Description
The DS26900 is a JTAG signal multiplexer providing
connectivity between one of three master ports and
up to 18 (36 in cascade configuration) secondary
ports. The device is fully configurable from any one of
the
three
master
ports.
The
DS26900
can
automatically detect the presence JTAG devices on
the secondary ports.
The DS26900 can be used in multiple configurations
including as a single device, two cascaded devices,
or two redundant devices.
All device control and configuration is accomplished
through standard JTAG operations via the selected
master port.
