Description

The IDT72V8988 is an ST-BUS®/GCI compatible digital switch controlled by a microprocessor. The IDT72V8988 can handle as many as 128, 64 Kbit/s input and output channels. Those 128 channels are divided into 4 serial inputs and outputs, each of which consists of 32 channels. The IDT72V8988 provides per-channel variable or constant throughput delay modes and microprocessor read and write access to individual channels. As an important function of a digital switch is to maintain sequence integrity and minimize throughput delay, the IDT72V8988 is an ideal solution for most switching needs.
