the m29323/6 provides a complete physical-layer solution for flexible ds3/e3/sts-1 clear channel services. the m29323/6 aggressively drives down cost for existing solu- tions and as well as reduces pcb real-estate and power. each port of the m29323/6 operates independently allowing for a mix of ds3, e3 or sts-1 on the same device. this enables adms/oeds and mspps to deploy a single line card that supports the simultaneous mapping for sdh or sonet transport of both ds3 and e3. the m29323/6 includes 3/6 independent ds3/e3/sts-1 line interface units (lius) with built-in digital jitter attenuators (djat), 6/12 ds3/e3 framers and 3/6 sts-1 framers. each port is capable of supporting ds3/e3/sts-1 mapped/demapped signals to/from sonet/sdh. the m29323/6 line side interfaces support electrical ds3/e3/sts-1, requiring only the addition of transformers and passive termination. the m29323/6 system interface supports sts-12/stm-4 for the sonet/sdh traffic via a standard 8-bit, 77 mhz tdm telecom bus. thus, a channelized oc-12/stm-4 or oc-3/stm-1 can be broken down to ds3/e3/sts-1 streams by the m29323/6 on a channel-by- channel basis. the m29323/6 requires only one 19.44 mhz reference clock (passive crystal) or 77.76/155.52 mhz sonet reference clock for generating all the necessary internal line rate clocks. the generated clocks are also available through an output pin. in addition, the m29323/6 supports pseudo-random bit sequence (prbs) testing and a full set of loopback functions at different functional blocks. using the telecom application package (tap) software to abstract the physical registers, developers can easily implement the m29323/6 solution, reducing design time. the m29323/6 are offered in a 27mm fcbga package. > high integration C lius with djat, ds3/e3 framers/mappers, sts-1 framers/mappers, sts- 12/stm-4 framer > flexibility C mix ds3, e3 and sts-1 on one device > easy implementation C tap software + high integration = faster time-to-market > parallel 8-bit, 77.76 mhz tdm telecom bus > embedded clads for supported line rates > pattern generator/detector for bert > comprehensive loopbacks > > key features 3/6-port ds3/e3/sts-1 integrated line termination device for transport m29323/6 Cline-card-on-a-chip
