Synchronous Serial Interface Port
The Z02201 interface consists of the Synchronous Serial Interface Port, 8-bit Host
Microprocessor Interface, Eye Pattern Interface, Voice Band AFE, System Sig-
nals, and Overhead Signals. The Z02201 functional interconnect diagram is indi-
cated in
signal name.
The Synchronous Serial Interface Port provides no parallel-to-serial/serial-to-par-
allel conversion hardware. The synchronous serial interface port consists of six
signal pins as shown in
