DS317x is a Maxim integrated DS3/E3 framer and LIU device that interfaces to as many as four DS3/E3 physical copper lines.
The Maxim DS317x family (DS3171, DS3172, DS3173, DS3174) provides single‑chip DS3/E3 transceivers with integrated line interface units (LIU) and framers. Each device supports up to four DS3/E3 copper lines, independent port configuration, and built‑in HDLC controllers.
The document includes functional diagrams, detailed pin descriptions, electrical and timing characteristics, package information, and JTAG test port details, enabling designers to integrate the devices into access concentrators, multiplexers, routers, and other telecommunications equipment.
