The BCM93214 is a DOCSIS/EuroDOCSIS-2.0 based
cable modem termination system (CMTS) reference
design incorporating:
• 64/256/512/1024 QAM downstream modulation with FEC
• QPSK, 16, 32 and 64 QAM burst ATDMA demodulation
• Digitally generated IF carrier that meets
• DOCSIS/EuroDOCSIS programmable downstream transmit IF
• Master/Slave MAP, reference clock, timestamp synchronization,
• BCM3214 MAC hardware that simplifies registration, ranging,
• Scheduler support for DOCSIS 2.0 best-effort, polled, and
The BCM93214 basic system parameters include:
• A BCM3214 Compact PCI V2.1 compliant base board with
