Standard packet, cell, and circuit interfaces are tightly coupled with the high-performance communications processing engine in order to support WAN edge applications. The Level II compliant, packet-extended UTOPIA port operates as an 8-bit bidirectional interface and supports master or slave mode. The UTOPIA port supports 52, 56 and 60 byte cells and a POS PHY interface mode. The host interface for the CX27510 is provided by a revision 2.2/2.1 compliant PCI interface. Byte lane swap capabilities are provided for ease of design in Little Endian systems. The TDM interfaces can support 24, 32, 64, 96 or 128 DS0 timeslots for T1/E1 interfaces or computer telephony busses. The TDM interfaces provide inline CAS support, DS0 tri-state control, independent TX and RX clocks, and multi-frame synchronization. Support for adaptive and SRTS clocking is supported without need for external circuitry.
