The CX29600 provides the following general system features:
The CX29600 provides the following transmitter features:
• An 8-bit microprocessor interface that supports the Mindspeed EBUS
• A one-second input, with a one-second output derived from an 8 kHz clock
• A default mode of operation (from reset) with the following:
• Maps STS-1 SPEs into STS-3 frame structures.
• Generates section, line, and path overhead.
• A single serial LVPECL interface for STS-3 operation.
• 8-bit SI-Bus interfaces on the system side.
• Serial clock and data interfaces to external circuitry for acess to section
• A frame reference input to allow the transmit frame to be synchronized
• A transmit frame reference output to indicate the relative position of the
• Transmitter frame scrambling using the x7 + x6 + 1 polynomial is enabled
• All zeros data in the transmit frame (after scrambling) can be generated by
