LXP730

www.DataSheet4U.com LXP730 Multi-Rate DSL Framer Datasheet The LXP730 is a multi-purpose Digital Subscriber Line (DSL) framer which complements the Level One SK70725/21 Enhanced MDSL Data Pump (EMDP) to provide seamless transport of data and voice signals over one or more DSL datapaths. Applications The LXP730 in combination with the EMDP chipset is optimized for use as a framer or I/O interface device for the following applications: s Digital Pair Gain Systems s Ethernet Modems s s s s T1/E1 Fractional Transport Systems Videoconferencing Systems Simultaneous Data - Voice Transport Systems Wireless Base Station Access Systems Product Features The LXP730 provides the basic functions required of a DSL framer: s Synchronization of external data streams to the DSL line s Multiplexing and demultiplexing of independent data streams for voice and data s Loopback of payload data at the DSL interface s Creation, insertion, and recovery of the MDSL Overhead (MOH) structure, performance monitoring, and message transport required in a DSL system with a capacity of up to 32 kbps s s s s Supports two input/output data streams simultaneously — Slave mode: external clock determines the rate at which data will be transferred to and from the framer — Master mode: clock derived from received DSL clock or external oscillator Single part architecture allows one chip to be used economically in both central and remote locations Supports systems with point-to-point architectures Alternate Ha...
