CN8330
DS3/E3 Framer with 52 Mbps HDLC Controller
The CN8330 is an integral DS3/E3 framer designed to support the transmission formats defined by ANSI T1.107-1988, T1.107a-1989, T1.404, and ITU-T G.751 standards. All maintenance features required by Bellcore TR-TSY-000009 and AT&T PUB 54014 are provided. In addition, the CN8330 can be optionally configured as a High-Level Data Link Controller (HDLC) usable with or without DS3/E3 framing overhead. The CN8330 provides framing recovery for M13, C-bit parity, Syntran, and G.751 E3 formatted signals. A First In First Out (FIFO) buffer in the receive path can be enabled to reduce jitter on the incoming data. Transmit and receive data is available to the host in either serial or parallel byte and nibble formats.
