SC2000 Datasheet PDF - Philips Electronics

OVERVIEW
The SC2000 is a custom VLSI circuit optimized for use in the call processing environment. The SC2000 provides a cost-effective means of implementing the interface between a high speed internal TDM bus and an external (expansion) TDM bus. Internal buffering allows the exchange of data between TDM buses of different speeds and architectures.

FEATURES
• Multi-time slot switching capability for N x 64K channels (N = 1 to 32).
• Architecture optimized for the call processing environment: SCSA TM, PEBTM, or MVIPTM compatible.
• Two software selectable expansion bus formats:
    • SCbusTM /ST-BUSTM
    • 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
• 5v CMOS technology
