P-LCC-44-1
• Switching of 16-, 32-, or 64-kbit/s channels
• Two consecutive 64-kbit/s channels can be switched as a single 128-kbit/s channel
• Freely programmable time slot assignment for all subscribers
• Two serial interfaces (PCM and CFI) programmable over a wide data range (128 -
8192 kbit/s)
• Data rates of PCM and configurable interface independent from each other (data rate
adaptation)
• PCM-interface
– Tristate control signals for external drivers
– Programmable clock shift
– Single or double data clock
• Configurable interface
– Configurable for IOM-, SLD- and PCM-applications
– High degree of flexibility for datastream adaptation
– Programmable clockshift
– Single or double data clock
• Synchronous µP-access to two selected channels
