Mapper IMUX Ethernet 10Mbps/100Mbps 1.8V/3.3V 169-Pin CSBGA

The DS33Z41 extends a 10/100 Ethernet LAN segment by encapsulating MAC frames in HDLC or X.86 (LAPS) for transmission over up to four interleaved PDH/TDM data streams using robust, balanced, and programmable inverse multiplexing. The Interleave Bus (IBO) serial link supports seamless bidirectional interconnection with Dallas Semiconductor"s T1/E1 framers and transceivers. The device performs store-and-forward of packets with full wire-speed transport capability. The built-in Committed Information Rate (CIR) Controller provides fractional bandwidth allocation up to the line rate in increments of 512kbps.
