ML53612中文资料冲电线数据手册PDF规格书

DESCRIPTION

The ML53612 is a complete CT Bus system interface and time-slot interchange device that provides a cost-effective connection between a computer board’s telephony interfaces or signal processing resources and the CT Bus. The ML53612 is an evolution of existing time-slot interchange ICs which offers seamless interoperability with SCbus devices.

FEATURES

• 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.

Applications

• Low- to medium-density computer telephony hardware (PCI and cPCI platforms)

• Enhanced service platforms

• Private branch exchanges (PBXs)

• Wireless base stations

• Internet telephony systems

• Digital trunking equipment
