and write access to individual channels. As an important function of a digital
switch is to maintain sequence integrity and minimize throughput delay, the
IDT72V8985 is an ideal solution for most switching needs.
FUNCTIONAL DESCRIPTION
Frame sequence, constant throughput delay, and guaranteed minimum
delay are high priority requirements in today鈥檚 integrated data and multimedia
networks. The IDT72V8985 provides these functions on a per-channel basis
using a standard microprocessor control interface. Each of the eight serial lines
is designed to switch 64 Kbit/s PCM or N x 64 Kbit/s data.
In Processor Mode, the microprocessor can access the input and output time
slots to control other devices such as ISDN transceivers and trunk interfaces.
Supporting both GCI and ST-BUS
廬
formats, IDT72V8985 has incorporated an
internal circuit to automatically identify the polarity and format of the frame
synchronization.
A functional block diagram of the IDT72V8985 device is shown on page 1.
The serial streams operate continuously at 2.048 Mb/s and are arranged in
125碌s wide frames each containing 32, 8-bit channels. Eight input (RX0-7) and
eight output (TX0-7) serial streams are provided in the IDT72V8985 device
allowing a complete 256 x 256 channel non-blocking switch matrix to be
constructed. The serial interface clock for the device is 4.096 MHz.
DESCRIPTION:
The IDT72V8985 is a ST-BUS
廬
/GCI compatible digital switch controlled by
a microprocessor. The IDT72V8985 can handle as many as 256, 64 Kbit/s input
and output channels. Those 256 channels are divided into 8 serial inputs and
outputs, each of which consists of 32 channels. The IDT72V8985 provides per-
channel variable or constant throughput delay modes and microprocessor read
