TSIP on C6452 Provides VoIP Apps More Performance While Increasing Robustness and Flexibility

• Increased system performance through improved synchronization and frame management –

– Each TSIP can support 2x the Time Division Multi-plexed (TDM) Time slots of a McBSP in this type of application

• Robust Serial Interface– TSIP provides better response

for recovery to serial clock & frame sync issues

• Flexibility– Each slot can independently select

alaw, µlaw, or linear – Add or drop time slots on the fly
