Description
The SC2009ABR is a custom VLSI circuit designed specifically for use in call processing environments. It serves as an interface between a high-speed internal TDM bus and an external expansion TDM bus. With internal buffering, it allows for the exchange of data between TDM buses of different speeds and architectures.
Specifications and features
- Multi-time slot switching capability for N x 64K channels (N = 1 to 32) - Architecture optimized for the call processing environment: SCSA™, PEB™, or MVIP™ compatible. - Two software selectable expansion bus formats: SCbus™ / ST-BUS™, PEB. - Two software selectable local bus formats: ST-BUS, PEB. - Enhanced input hysteresis threshold. - 32 x 2048 channel switch. - Serial or parallel access to the SCbus. - Internal support for SCbus clock fallback. - Built-in SCbus message bus interface. - Supports both Intel® and Motorola® processor interfaces. - 68-pin PLCC package. - Uses 5V CMOS technology.
Application Scenarios
The SC2009ABR is ideally suited for use in call processing systems that require an interface between different TDM buses. It can be used in telecommunications networks, digital exchanges, and any system that relies on the exchange of data between TDM buses.
Comparison
Advantages- Allows for data exchange between TDM buses of different speeds and architectures. - Multi-time slot switching capability offers flexibility in channel selection. - Supports both Intel® and Motorola® processor interfaces, providing compatibility with different systems. - Built-in SCbus message bus interface simplifies communication between components.
Disadvantages- Limited to 32 x 2048 channel switch.
