Manufacturer:NS Description: Frame sequence, constant throughput delay, and guaranteed minimum delay are high priority requirements in todays 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® 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 125µs 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. |
