Pin Description
Note 1:
The DSO/DSI serial port terminals have been arranged such that when one device is rotated 180 degrees with respect to the other device the serial
connections will properly align without the need for any traces or cable signals to cross. Other layout orientations may require that traces or cables cross.
Control Logic Circuitry
The FIN12AC has the ability to be used as a 12-bit Serial-
izer or a 12-bit Deserializer. Terminals S1 and S2 must be
set to accommodate the clock reference input frequency
range of the serializer. The table below shows the terminal
programming of these options based on the S1 and S2
control terminals. The DIRI terminal controls whether the
device is the serializer or a deserializer. When DIRI is
asserted LOW, the device is configured as a deserializer.
When the DIRI terminal is asserted HIGH, the device will
be configured as a serializer. Changing the state on the
DIRI signal will reverse the direction of the I/O signals and
generate the opposite state signal on DIRO. For unidirec-
tional operation the DIRI terminal should be hardwired to
the HIGH or LOW state and the DIRO terminal should be
left floating. For bi-directional operation the DIRI of the
master device will be driven by the system and the DIRO
signal of the master will be used to drive the DIRI of the
slave device.
Turn-Around Functionality
The device passes and inverts the DIRI signal through the
device asynchronously to the DIRO signal. Care must be
taken by the system designer to insure that no contention
occurs between the deserializer outputs and the other
devices on this port. Optimally the peripheral device driving
the serializer should be put into a HIGH Impedance state
prior to the DIRI signal being asserted.
When a device with dedicated data outputs turns from a
deserializer to a serializer the dedicated outputs will remain
at the last logical value asserted. This value will only
change if the device is once again turned around into a
deserializer and the values are overwritten.
