ML53612

• High functionality, low cost implementation of the ECTF H.100/H.110 interoperability specifications.
• Simple to connect PCI and cPCI™ board-level circuitry to the universally accepted CT Bus™.
• Ultra slim profiling (176-pin LQFP package).
• Up to 128 programmable connections (64 transmit and 64 receive) to any of the 4096 timeslots on the H.100/H.110 CT Bus.
• 8-channel stream-to-stream switching for data stream connections at variable rates.
• Implementation of all compatibility signals for complete interoperability with existing 4 MHz SCbus™, 8 MHz SCbus, 2 MHz MVIP-90™ devices, and H-MVIP™.
• Master PLL meets AT&T 62411 MTIE and jitter attenuation requirements to provides reliable clock synchronization for network-grade connection to digital network interfaces.
• Supports all H.100/H.110 CT Bus clock fallback features.
• Choice of constant or minimum switching delay on a per time-slot basis.
• 3.3 V I/O with 5 V tolerant input.
• Supports multiplexed and nonmultiplexed address/data bus modes for both Intel and Motorola microprocessors.
• Supports CT Bus optional message channel interface, for both H.100 (PCI) and H.110 (cPCI) applications.
• Supports a variety of framing formats via a configurable local bus.
• Efficient microprocessor interface access to Local and CT Bus data streams through direct parallel access to/from transmit and receive switch.
• Direct Parallel Access to/from Transmit and Receive switch allows efficient microprocessor interface access to local and CT Bus data streams.
