The BCM93212 CMTS supports the DOCSIS/EuroDOCSIS 1.0 and 1.1 specification enabling QoS for the simultaneous processing of voice, video and data on a prioritized basis. The BCM93212 CMTS includes the BCM3034 Universal Advanced PHY QAMLink(R) Modulator, the BCM3212 DOCSIS/EuroDOCSIS 1.1 CMTS MAC and the BCM3138 Universal TDMA Burst Demodulator and provides all the necessary functionality required to receive and transmit high rate digital data to and from a cable plant. Functions include: * Hardware-supported messaging (ranging, registration, channel configuration) Downstream SDRAM (PHS, output queues) Memory The BCM93212 is complemented at the subscriber end by the BCM93345, BCM93350 and the BCM93360, DOCSIS/EuroDOCSIS-based cable modem and residential gateway silicon solutions. The BCM93360 is based on the BCM3360 single-chip residential gateway, which integrates all the major functions of a cable modem into a single device. Together, the BCM93212 and the BCM93360 provide vendors with a seamless end-to-end silicon solution for development and testing of an DOCSIS/EuroDOCSIS-based cable modem and cable modem termination system with TDMA upstream and advanced PHY downstream functions.
