VSC9675
An 84-channel T1 Framer with Integrated M13 and Provides up to 3 Channels of T3 Framing and Multiplexing. GENERAL DESCRIPTION: 3 channels of T3 framing and multiplexing. This highly flexible device accepts 2-pin Clock/Data or 3-pin Clock/Pos/Neg from an LIU, or 3-pin Clock/Data/FP from an external DS3 Framer. The VSC9675 uses a unique; patent pending, scalable time-sliced state machine architecture with internal context RAM to share logic for framing, error and performance monitoring, Facility Data Link (FDL) and Maintenance Data Link (MDL), robbed-bit signaling, slip buffers and other functions. The advantage of a shared state machine and shared RAM architecture is reduced gate count; resulting in a high density, low power design. Three methods for system-side connection to the VSC9675 are provided: 1) A standard Clk/Data for generic system connectivity, or 2) A high speed interface to a TDM backplane or standard time-slot-interchange, or 3) Vitesse open-architecture TDMe serial interface connecting the VSC9675 to the VSC9680.
