CN8478/CN8474A/CN8472A/CN8471A
Multichannel Synchronous Communications Controller (MUSYCC™)
Product Description
The CN8478, CN8474A, CN8472A, and CN8471A are advanced Multichannel
Synchronous Communication Controllers (MUSYCCs) that format and deformat up
to 256 (CN8478), 128 (CN8474A), 64 (CN8472A), or 32 (CN8471A) HDLC
channels in a single CMOS integrated circuit. MUSYCC operates at Layer 2 of the
Open Systems Interconnection (OSI) protocol reference model. MUSYCC provides
a comprehensive, high-density solution for processing HDLC channels for
internetworking applications such as Frame Relay, ISDN D-channel signaling,
X.25, Signaling System 7 (SS7), DXI, ISUP, and LAN/WAN data transport. Under
minimal host supervision, MUSYCC manages a linked list of channel data buffers
in host memory by performing Direct Memory Access (DMA) of the HDLC
channels.
MUSYCC interfaces with eight independent serial data streams, such as T1/E1
signals, and then transfers data across the popular 32-bit Peripheral Component
Interface (PCI) bus to system memory at a rate of up to 66 MHz. Each serial
interface can be operated at up to 8.192 MHz. Logical channels can be mapped as
any combination of DS0 time slots to support ISDN hyperchannels (Nx64 kbps) or
as any number of bits in a DS0 for subchanneling applications (Nx8 kbps).
MUSYCC also includes a 32-bit expansion port for bridging the PCI bus to local
microprocessors or peripherals. A JTAG port enables boundary-scan testing to
replace bed-of-nails board testing.
Device drivers for Linux, VxWorks
®
, and pSOS™ operating systems are
available under a no-fee license agreement from Conexant. The device drivers
include C source code and supporting software documents.
