Line Side Interfaces
Line Side Serial Interface
SONET Interleave Bus (SI-Bus) Interface
Two types of line side interfaces are provided: a serial DS3/E3 interface typically used
for a connection to an LIU device, and a parallel STS-1/TUG-3 interface used for a
connection to a SONET/SDH multiplexer device.
Serial line side interface allows the CX29503 to be connected to a LIU such as
Mindspeed’s CX28332 or CX28333 device. The interface allows for a full duplex
operation at the DS3 (44.736 MHz) and E3 (34.368 MHz) rates.
A receiver 16-bit FIFO buffer for reducing jitter on the incoming data is provided.
Each one of the three CX29503 line interfaces can be separately configured for an
independent DS3 or E3 operation.
A parallel STS-1/TUG-3 interface (SI-Bus) is provided for interfacing to a SONET/
SDH multiplexer device such as the CX29610. The interface consists of an 8-bit
parallel data bus in the transmit and receive directions, allowing for a full duplex
operation at the 19.44 MHz rate.
