Preliminary specification
30 Mbit/s to 3.2 Gbit/s A-rate
4-bit fibre optic transceiver
TZA3015HW
Line loop back mode
This mode feeds back the received serial data to the serial
data output together with the recovered serial clock. This
allows testing of the serial data path including the optic
fibres. The received serial data that is fed back is also
available in parallel format at the parallel output bus (see
Fig.17).
Diagnostic loop back mode
This mode feeds back the parallel input data to the parallel
outputs together with a parallel clock. The parallel data is
serialized and available at the serial output. Also a serial
transmit clock is generated. The parallel output clock
signal is recovered from the serial output data. This loop
mode is used to test the connection between the
transceiver and the data processing unit and the system
itself. No external fibre optic connection is needed to test
the system (see Fig.18).
Serial loop timing mode
This mode feeds back the recovered clock to the clock
synthesizer in order to run the receiver and transmitter at
the same clock frequency (see Fig.19).
