CX28342/3/4/6/8
Dual/Triple/Quad/Hex/Octal-Enhanced
DS3/E3 Framer
The CX28342/3/4/6/8 provides Dual, Triple, Quad, Hex, and Octal DS3/E3
framers designed to support DS3-M13, DS3-C-bit parity, E3-G.751, and
E3-G.832 transmission formats.
The CX28342/3/4/6/8 provides framing recovery for M13, M23, C-bit
parity, G.751, and G.832 formatted signals. A FIFO buffer in the receive
path can be enabled to reduce jitter on the incoming data. The CX28342/
3/4/6/8 devices allow for ease of configuration, while providing
maximum flexibility to support the transmission and recovery of industry
standard formats. It provides a flexible overhead bit generation method in
DS3/E3 modes to source overhead bits on an individual framer.
