DESIGN KIT AVAILABLE
DS3141/DS3142/DS3143/DS3144
Single/Dual/Triple/Quad
DS3/E3 Framers
www.maxim-ic.com
GENERAL DESCRIPTION
The DS3141, DS3142, DS3143, and DS3144
(DS314x) devices include all necessary circuitry to
frame and format up to four separate DS3 or E3
channels. Each framer in these devices is
independently configurable to support M23 DS3,
C-Bit Parity DS3, or G.751 E3. The framers interface
to a variety of line interface units (LIUs),
microprocessor
buses,
and
other
system
components without glue logic. Each DS3/E3 framer
has its own HDLC controller, FEAC controller, and
BERT, as well as full support for error detection and
generation, performance monitoring, and loopbacks.
